Ok, I got my two fields to add up and display in another field with this:
onchange="window.document.ExpenseForm.TotalAmount#Line#.value=parseFloat(window.document.ExpenseForm.Mileage#Line#.value)+parseFloat(window.document.ExpenseForm.CostOfMeals#Line#.value);addTotals();"
Now I'm trying to add up all the TotalAmounts and put it at the bottom of
the form. I need to loop through the entire list from 1 to #list# on each
onChange and update the GrandTotal. I can't figure out how to loop in
Javascript and hand it a dynamic variable name. I tried this:
<SCRIPT language="Javascript">
function addTotals()
{
i = 0
while (i <= #GetFormInfo.RecordCount#)
{
window.document.ExpenseForm.GrandTotalAmount.value=parseFloat(window.document.ExpenseForm.GrandTotalAmount.value)+parseFloat(eval("window.document.ExpenseForm.TotalAmount"+i+".value"));
i++
}
}
</SCRIPT>
But it doesn't work doesn't appear to go through each variable name. How
would I do this?
