Add number of business days to date field

Question

Hello, I noticed that there is not much discussion in the forum surrounding u201Cbusiness daysu201D so I hope this post/discussion/solution contributes to the content of this forum.
I am using the following 3 formulas to try to Add number of business days (based upon a table field) to a specified date:
1. Variable name = SetVar
//Set Variable for Add Business Days:
DateVar Array Holidays;
DateVar Target:= CDate({TMS_MOVEMENT_EVT.EVT_DATE}); // Put your field name in here
NumberVar Add:=  {DTCI_DOD_TRANS.TRANS}; // put the number of days here to add (a positive number)
NumberVar Added := (0);
2. Variable name = AddBizDays
//Adding Business Days:
EvaluateAfter({@SetVar});
WHILE Added < Add
Do (target := target +1;
    if dayofweek (target) in 2 to 6 and not (target in holidays)
        then Added:=Added+1
        else Added:=Added);
Target
3. Variable name = HOLIDAYS
//Holiday Array Formula for the report Header:
BeforeReadingRecords;
DateVar Array Holidays := [
Date (2003,12,25),   // you can put in as many lines for holidays as you want. 
Date (2003,12,31)
0
I am successfully getting my data needed to make the necessary calculations and variable assignmentsu2026 I believe that my ISSUE is that I am not sure where to place these formulas into my report so they assign the variables and execute properly when previewing my report. I am curious if that is my issue, and if so, can someone provide me direction on where to put each of these formulas in my report.
Currently, when I try to preview the report, I get the following Crystal Reports Error:  -u201CA number, currency amount, Boolean, date, time, date-time, or string is expected here.u201D
Then Crystal automatically opens the AddBizDays formula and highlights the word added, see below RE: u201CWHILE Addedu201D
For reference, my report has 3 groups, and I am displaying all of my output information (and locating my formulas) in the group footer #3 report section. I have moved them around to other report sections/groups/placements, but to no success.
Thanks so much.
Best, Matt

I worked this out... FYI - for the benefit of all forum users:
ADDING BUSINESS DAYS TO A CERTAIN DATE (excluding weekends and holidays)
1. Variable name = AddBizDays
//Adding Business Days:
WhileReadingRecords;
DateVar Array Holidays;
DateVar Target:= CDate(); // Put your field name in here
NumberVar Add:=  ; // put the number of days here to add (a positive number)
NumberVar Added := (0);
WHILE Added < Add
Do (target := target +1;
    if dayofweek (target) in 2 to 6 and not (target in holidays)
        then Added:=Added+1
        else Added:=Added);
Target
2. Variable name = HOLIDAYS
//Holiday Array Formula for the report Header:
BeforeReadingRecords;
DateVar Array Holidays := [
Date (2003,12,25), // you can put in as many lines for holidays as you want.
Date (2003,12,31)
0
...too bad i don't get forum points for sharing this solution.
