forgot the .values on the end of each var, that's why it was putting in [object],
should work now.

thane,
it's trying to concatenate them instead of adding, try something like this(forcing the
values into numbers then adding them):
<input type="Text" name="CostOfMeals#Line#" value="0" validate="float"
required="Yes" size="5" maxlength="5"
onchange= "
var num1=new Number(eval(window.document.ExpenseForm.Mileage#Line#.value);
var num2=new Number(eval(window.document.ExpenseForm.CostOfMeals#Line#.value);
window.document.ExpenseForm.TotalAmount#Line#.value = num1 + num2;
">

Subject: Adding two fields and displaying in a third
I'm writing a form that allows a person to fill in the mileage and meal
expense, and then displays the total in a third field. I'm using this in
the meals expense field:
<input type="Text" name="CostOfMeals#Line#" value="0" validate="float"
required="Yes" size="5" maxlength="5"
onchange="window.document.ExpenseForm.TotalAmount#Line#.value=eval(window.document.ExpenseForm.Mileage#Line#)+eval(window.document.ExpenseForm.CostOfMeals#Line#);">
But the third field evaluates to [object][object]. How do I get this to
add up?
