Help with validation on a manually created tabbed form

Question

version 4.1.1.00.23
Hello,
I have a manually created tabbed form that I'm having trouble creating validation on.
The page is a Resource Staffing page where PM's can forecast the Resources that will be needed for various projects. The forecast can be for 12 - 18 months.
The requirement is to display a message to the user if they are trying to save a row without forecasting any time. It's possible they may not know how may Resources or the length of time needed when the row is created.  If they respond that they want to save the row without time the MRU will create the record. If they answer that they do not want to save the row they are returned to the page without loss of information.
The month fields on the page are defaulting to 0 (zero).
I've updated the Save button to Redirect to URL and in the URL Redirect I have: javascript:confirmNoTimeSaved()
The javascript:
[code]
function confirmNoTimeSaved()
    var arr_jan,arr_feb,arr_mar,arr_apr,arr_may,arr_jun,arr_jul,arr_aug,arr_sep,arr_oct,arr_nov,arr_dec = new Array();
        arr_jan = document.wwv_flow.f07;
        arr_feb = document.wwv_flow.f08;
        arr_mar = document.wwv_flow.f09;
        arr_apr = document.wwv_flow.f10;
        arr_may = document.wwv_flow.f11;
        arr_jun = document.wwv_flow.f12;
        arr_jul = document.wwv_flow.f13;
        arr_aug = document.wwv_flow.f14;
        arr_sep = document.wwv_flow.f15;
        arr_oct = document.wwv_flow.f16;
        arr_nov = document.wwv_flow.f17;
        arr_dec = document.wwv_flow.f18;
    for(i = 0; i < arr_jan.length; i++)
        if(arr_jan[i].value == 0 && arr_feb[i].value == 0 && arr_mar[i].value == 0
            && arr_apr[i].value == 0 && arr_may[i].value == 0 && arr_jun[i].value == 0
            && arr_jul[i].value == 0 && arr_aug[i].value == 0 && arr_sep[i].value == 0
            && arr_oct[i].value == 0 && arr_nov[i].value == 0 && arr_dec[i].value == 0)
            txt = 'You have no time assigned to your Forecast. Do you want to save this Forecast without time entered?' + '\n' + '\n' + '"Yes" to save the Forecast.' + '\n' + '"No" to return with no changes.';
            caption = 'Confirm Saving With No Time';
            vbMsg(txt,caption)
            switch (isChoice)
                case 6:
                    doSubmit('SUBMIT');
                    break;
                case 7:
                    doSubmit('CANCEL2');
                    break;
        else
            doSubmit('SUBMIT');   
            break;
</script>
<script language="VBScript">
<!--
//Yes    = 6
//No     = 7
    Function vbMsg(isTxt,isCaption)
        testVal = MsgBox(isTxt,vbYesNo,isCaption)
        isChoice = testVal
    End Function
//-->
</script>
[/code]
The 'CANCEL2' is just a Branch I'm using to branch back to the page without clearing Cache. I do have 'Cancel' button on the page and the Branch created for that clears the Cache.
While debugging the javascript I get into the VB Script on the testVal = MsgBox(isTxt,vbYesNo,isCaption) line and the browser crashes.
Can someone help with this requirement?
What additional information can I provide?
Thanks,
Joe

Answer 1

The code above is my attempt at this requirement, however, the browser crashes when it gets to the VBScript on the MsgBox call. I don't have to use this approach. Does someone have an idea how to solve this?
Thanks,
Joe
