I'm trying to create a form that has two numeric input fields (say FieldA and FieldB).

What I want to do is have the sum of FieldA and FieldB displayed on the same form after the user enters the values. I've been playing with the MATH tag, but can't seem to figure out how to automatically display the updated value on the form.

Any suggestions?

Hi,

Try doing it the following way.

Do an lxFetch on the onblur event of the second input field that way you have values from both the input fields and then in your actions do a MATH that calculates the sum.

For ex:
<input type="text" name="field1" id="field1" value="[field1,F]" />
<input type="text" name="field2" id="field2" value="[field2,F]" onblur="lxFetch('[MODULEID<SYSTEM]',0,'flag=Calc');"/>

In your actions:
#If '[flag,Q]'='Calc'
##Assignment Action Name Calculate: {MATH,([field1,F]+[field2,F])}

## - child of 'If' action

You can access the calculated value as [Calculate,Action]

Hope this helps.

Thanks,
