Dropdown Form field calculation

[lacviet2005]

Hi guys,
I have two dropdown FORM fields with numbers and want to do a calculation on them? Is it possible?

I've tried this but didn't work :doh:
=Dropdown1+Dropdown2

Thanks,
LV

If they are formfield dropdowns, you need to get the value of them. Dropdown1 does not give its value.

You shoud rename them.

How are you firing your code, an OnExit macro?
