Roi,
the textboxes change due to interactivechange events of combos on the form. does that have anything to do with it? and does the totalbdft() function need to be in the interactivechange of all involved objects?

It'll probably be pretty confusing at first but look at the Trace window. that will show the code currently being run and a little pointer will tell you what line your are at. You can hover your cursor over vars and properties and the tooltip will tell it's current value. That way you can see what VFP is doing.

>>>example:
>>>
>>>

WITH THISFORM
>>>	.totalbdft.VALUE = ;
>>>		VAL( .bdft1.VALUE ) + ;
>>>		VAL( .bdft2.VALUE ) + ;
>>>		VAL( .bdft3.VALUE ) + ;
>>>		VAL( .bdft4.VALUE ) + ;
>>>		VAL( .bdft5.VALUE ) + ;
>>>		VAL( .c16.VALUE   ) + ;
>>>		VAL( .bdft7.VALUE ) + ;
>>>		VAL( .bdft8.VALUE )
>>>
>>>	.totalbdft.REFRESH()
>>>ENDWITH

>>>You can also use the ; to continue lines of code on more that one line, and use spaces to line things up. Makes it a little easier to read :)

>>>Also I don't think you need the val() function. If you get a "function invalid" type message (like I got when testing it) just delete the val() from the above.
