Hi. Very simple request: I need a PDF for which takes a price entered in one field, multiplies by 3, checks a button to see if VAT is to be added at 17.5% and if so adds it to the total, then sets a second read-only field to the result.
I've tried all sorts of things in the custom calculation but I can only get the AFSIMPLE_CALCULATION function to work and that's not adequate. This is so trivial compared to some PDFs I've seen and used that it must be doable, but how? Where does the code, in particular the "IF button pressed" part, go? Thanks, Thomas Worthington
