Hi Niall,I'm pretty sure that I have done everything on my form as you
have described. As I mentioned before, it's wierd because as long as you
don't change the code at all, the script works fine (as in Johns
example) but when it has been changed, the checkboxes are just inactive.
Try it using Johns example, change the max vaule to 2 in the
setminandmax function in the second subform and switch to the PDF
preview tab. That part of the form suddenly stops working even though
you have only changed...
