Field average calculation

I am designing an Employee Review form and in that form I have a field that calculates the average of a set number of other fields. The problem is that the users can enter 1-5 or n, where n = no experience. I want the average field to only average the fields with 1-5 in them and skip the n fields. I have tried multiple ways of acomplishing this, but none have worked. Really could use some help on this one!!

Have you tried a "Custom Calculation Script"?
A custom calculation script will required the use of specific field names to be processed.
Unless you are computing the average on all items you might consider using a function for counting and summing the fields and values in a range of questions.
Since it is possible that no questions could be answered, you need to allow for a count of zero items being used for the computation.

  • Bug average calculation in form?

    Hye,
    I made an editable form in acrobat XI for mac.
    I set all the fields to number and the last field I want to calculate the average of all the other fields.
    So I select the fields which average I want...
    But upon testing, I'm getting impossible average calculations.
    F.ex. testing several fields with value "9", returns me a "0,..." value, which is impossible...
    How to solve?
    Thanks

    It's hard to say what's happening without seeing a sample. Can you post one somewhere? Unfortunately, you can't post one here, but can at Acrobat.com, dropbox, skydrive.com, etc.

  • Add average calculation to FBL5N?

    Hi,
    My user requires an average calculation on one of the columns in FBL5N (customer line items).  This is a standard transaction which uses an ALV.
    I know that I can add new fields into this transaction using customizing but I need an average, so would need to create a new field and populate it with strange looking numbers in order to get an average total at the bottom.
    I have seen an average calculation button on some ALVs and was wondering if it's possible to change the ALV settings in the code of FBL5N in order to get this to show?  At the moment I can only total and subtotal, there is no average calculation button showing.
    Or, if you can think of another solution, any suggestions gratefully received.  The last resort is asking the user to download the data to excel and calculate the average there.
    Thanks,
    Gill

    hi
    select the column,  which u have to calculate the average .
    and select edit menu ->calculate->Mean value

  • Baseline Duration custom field not calculating duration properly

    Hi,
    I am using MS Project server 2010. In it, I created one custom field named 'Baseline_Duration' similar to 'Baseline Duration' & applied the formula 'ProjDateDiff([Baseline Start], [Baseline Finish], "Standard")'. In Baseline_Duration
    & Baseline Duration columns, values should be same. But for some tasks, values in Baseline_Duration column is different from Baseline Duration column, & for other tasks, both are same.
    Please suggest me why values in both columns are different for some tasks?
    Thanks & Regards Pradeep Gangwar

    Pradeep,
    It sounds like the issue might be within the setting for that 'Baseline_Duration' field and calculations
    for summary rows.
    In cases where Baseline Duration was saved for individual tasks without rolling up to summaries rows - you may have deviations. Applying "Use Formula"
    for summary rows should do the trick.
    Regards,
    Alex

  • How can I activate the average calculation with cl_salv_hierseq_table class

    Hi there,
    Iu2019m using class cl_salv_hierseq_table to display a two level hierarchy (header and item) list.
    For some reason it seams that those calculations are active by default with class cl_salv_table but not for cl_salv_hierseq_table.
    I tried every suggestion from the class documentation and SAP help and nothing seams to work, the menu calculation options are always inactive except for the total calculation.
    After the cl_salv_hierseq_table=>factory...
    And before cl_salv_hierseq_table->display( )
    I triedu2026u2026.
    cl_salv_aggregations = cl_salv_hierseq_table->get_aggregations( 1 )
    cl_salv_aggregations->add_aggregation( 'COLUMN1' )
    COLUMN1 is a currency column in header level table
    u2026u2026..
    cl_salv_aggregations = cl_salv_hierseq_table->get_aggregations( 2 )

    Any help will be appreciated!

    Thanks Harsh Bhalla,
    Subtotals can be built (displayed) at Header Level Only, true but the values to calculate those totals can come from either header or item level, otherwise it wouldnu2019t be of much use would it?
    Anyway my question is how to activate the average calculation as well because the totals calculations is already active for either item or header level by default.
    For reference when on the display layout Iu2019m referring to the menu Edit -> Calculate -> Mean Value.

  • Average Calculation

    Hi,
    I am finding some problem while doing the Average Calculation in the Query.
    My data is like this:

    B1           1000         1000               200
    B1           1000         1000               500
    In the output I want:

    B1           700                    300
    The calculation for Unallocated is ( Stock - Allocated ).
    Right now I am getting:
    Batch      Allocated           Unallocated
    B1           700                   1300
    What I want is to do the Average of the Stock Qty and then subtract that from the Allocatde Qty.
    Can anyone help out?

    The alias 'b' does not exist outside of the subquery/inine view. Try to alias your subquery for clarity then refer to it;

    FROM (SELECT ts_desc,
                 ts_remarks,

          FROM t_status_report b, t_task_status a
          WHERE b.sr_id = a.ts_srid) sub
    GROUP BY ROLLUP(ts_desc,

  • GrandTotal Average calculation.

    Hi
    My report has following fields.
    Tower, Prjid, Rating.
    I want to dispaly total number projects and average rating of projects  for each tower.
    so i group the data by towr wise.
    i am using this formula to calucate toweraverage rating
    @toweravg= Sum ({TOWERSUMMARY.OverallRating}, {TOWERSUMMARY.Tower}) / Count ({TOWERSUMMARY.ProjectCSSId}, {TOWERSUMMARY.Tower})
    for calculating grandavg i am using
    avg(@toweravg) , but this formula showing error liike  This field can not be summarized.
    So how to calculate grandtotal of  avg?
    sample data:
    1 4.00
    2 2.50
    i want in the end like
    3   3.25((4.00+2.50)/2)

    I am asuming you are getting 4.50 and 2.00 from this
    Count ({TOWERSUMMARY.ProjectCSSId}, {TOWERSUMMARY.Tower}
    You have to use the same without the last bit i.e.
    Count ({TOWERSUMMARY.ProjectCSSId})
    and place it under Report footer.
    This will count all of the above.
    Then use that and take average.

    I would like to be able to search by kids age and get the info displayed when doing slideshows.
    How to do this in iPhoto ?
    Any alternatives to accomplish the same ?
    Kind regards

    It can't be done with iPhoto.  There are some DAM (digital asset management) applications that can write to other IPTC fields that iPhoto can't read. One such app is Media Pro 1.
    However you would have to calculate the age for each date and add it to one of the fields. There are online age calculators that can do that for you: Age Calculators
    If you go thru that much trouble then use iPhoto, make the calculations and add the age to the Description field.  Then you can use Smart Albums to search for 1year 6 month text.

  • Date field difference calculation

    Hi all,
    I am new to Adobe and Java scripting so apologies if this has already been answered elsewhere - I have not been able to find it if it has.
    I want to calculate the difference between two dates fields in hours and mins on a form.
    I have two fields, both Date format (dd/mm/yyy HH:MM), a Start and End date and I want the difference between them in the Time format HH:MM.
    Can anyone help me with the script for this? What I have so far is:
    var strStart = this.getField("StartTime").value;
    var strEnd = this.getField("EndTime").value;
    if(strStart.length || strEnd.length)
    var dateStart = util.scand("dd/mm/yyyy HH:MM",strStart);
    var dateEnd = util.scand("dd/mm/yyyy HH:MM",strEnd);
    var diff = dateEnd.getTime() - dateStart.getTime();
    // One Day = (24 hours) x (60 minutes/hour) x
    // (60 seconds/minute) x (1000 milliseconds/second)
    var oneMin = 60 * 60 * 1000;
    var mins = Math.floor(diff/oneMin);
    event.value = util.printd("HH:MM",mins);
    But this is not working...
    Mary

    The result can be formatted using:
    // format result using "h:MM" format
    event.value = util.printf("%,0 0.0f" + ":" + "%,002.0f", nHours, nMinutes);
    One cannot use the date or time formats since the time values will be limited to the hours and minutes values for 1 day, so any time value that is over 23 hours 59 minutes is not possible.
    A full script solution including document level functions for conversion of date strings to minutes and converting minutes to a time string:
    // reusable document level functions;
    function Time2Num(cFormat, cDate) {
    // convert date value with format to number of minutes form Epoch date;
    var oDate = util.scand(cFormat, cDate);
    var nMins =  null;
    if(oDate ==  null) app.alert("Error converting " + cString + " using " + cForamt);
    else nMins = oDate.getTime() / (1000 * 60);
    return Math.floor(nMins);
    } // end Time2Num format
    function Num2Time(cFormat, nMins) {
    // convert number of muniutes to h:MM or HH:MM format;
    // return formatted string for valid formats;
    // return null for invalid formats;
    var cElapsed = null;
    // test for nMins being a number;
    if(isNaN(nMins)) {
    app.alert("Minutes must be number",0, 0);
    } else {
    var nHours = Math.floor(nMins / 60);
    var nMinutes = Math.floor(nMins % 60);
    switch(cFormat) {
    case "h:MM":
    cElapsed = util.printf("%,0 0.0f" + ":" + "%,002.0f", nHours, nMinutes);
    break;
    case "HH:MM":
    cElapsed = util.printf("%,002.0f" + ":" + "%,002.0f", nHours, nMinutes);
    break;
    default:
    app.alert("Invalid format " + cFormat + "\nMust be \"HH:MM\" or \"h:MM", 0, 0);
    break;
    return cElapsed;
    } // end Num2Time function
    // end document level funcitons;
    // custom calculation script;
    event.value = ''; // clear result;
    var strStart = this.getField("StartTime").value;
    var strEnd = this.getField("EndTime").value;
    if(strStart.length || strEnd.length) {
    var nDateStart = Time2Num("dd/mm/yyyy HH:MM",strStart);
    var nDateEnd = Time2Num("dd/mm/yyyy HH:MM",strEnd);
    var nMins = nDateEnd - nDateStart;
    // format result using "h:MM" format
    event.value = Num2Time("h:MM", nMins);
    // end custom calculation script;

  • Accessing the field values in different fields for calculation

    Hi,
    I am creating a report in which I have used breaks for grouping the  customers by their category. I have used summary on the amount field to calculate the sum in the individual category and also for total amount.
    Now, I also want to add an column which could display the percentages of individual contributions.
    So, its like I have to write a query accessing the total percentage, categorized percentage and individual amount.
    My question: How can I access the various fields values in the query of some other field specifically sum and total sum( because it shows the sum([Amount]) for category sum and total sum both)
    -BOBJuser

    Hmmm, I assume you are talking about WebIntelligence here...
    Ok, so let's go: you can access every "object" in the report simply by it's name. Every cell contains either a constant value (e.g. some text) or a formula, the simplest one can be just the value of an "object" from the query.
    There is a formula bar on top which you can activate, where you can easily see the content of a specific cell and also copy/paste the formula from the cell, as well as access all the built-in functions.
    WebI has a built-in calculator which works very similar to a "micro" olap engine, so you can access every sort of aggregate (of a measure) via a correspondig formula, irrelevant in which cell you are using it.
    Nevertheless, there is a "computation context" which depends on the place where you put the formula, e.g. summary row, detail row, etc.
    for more info: see the manual )

  • Cannot select fields for calculating other fields~

    Help -- I am tryiing to get certain fiels in a form to calculate based on selection of other fields.  The fields to be selected already have values in them.  (The same format I have used for several years, just new set of forms)
    I get through the point of setting up the field properties to calculate and I select Sum of...   Then it simply will not let me select any fields to use for calculations -- unless I select all fields.
    Please -- this is time sensitive and urgent any help responses needed and welcome!

    Sounds like you are having issues with Acrobat and not FormsCentral. You would get a better help if you post your question on the Acrobat's forum
