Hi All
I am developing a transcript page for HS students to view their GPA.s and am running into a frustrating issue.
On a grid I display their courses and GPA scores.
I have a hidden field: tgpa which totals the gpa scores from all the courses in the grid
A hidden field: numc which retrieves the number of records in the grid.
And the gpa1 field which is supposed to divided tgpa by numc and come up with their gpa, but I get a 'Division by Zero' error.
Label 'gpa1': Before Show of the label( This is where the error comes from)
$Component->SetValue($ntran->tgpa->GetValue()/ $ntran->numc->GetValue() );
Hidden field 'tgpa': Before Show Row
$ntran->tgpa->SetValue($ntran->tgpa->GetValue() + $ntran->gpa->GetValue() );
Hidden Field 'Numc' : a 'retrieve number of records' action which is in the Before Show event
When I switch the hidden fields to labels, all the numbers for numc and tgpa display properly.
TIA
