I have had several cases where I've added a button to a form and when I use it to do something, upon return to the form, the previously hidden/exposed fields are correctly redisplayed but various fields are dead and do not accept input any more.
The simplest example is using a button to hide or display various fields on the same form. When I click on the button, the redisplay works, but some fields no longer function for data entry.
The first time this happened to me, I switched the button to a radio selection and then there was no problem with the functionality. The second instance, I'm updating another file on a separate popup form and HAVE to use a button to pop that up, so I can't think of a workaround as I could with the first instance.
I'm stumped and I have scoured the code.
Regards,
Mark
