Something tells me this is a simple problem, but I seem to be stuck.
I am working on a form in which there are two text fields which can
contain numerical values. But only one of them can have a value other
than zero. So if the first one has a value, the second one becomes
zero, and if you then enter a value in the second one, the first one
reverts to 0.
I didn't create this form originally and so I am working within some
constraints. I won't bore you with the details as to why, but this
can't be a form verification thing where you get a warning when both
fields have a nonzero value. It has to be where if you enter a value
in one, the other becomes 0 and vice versa.
Any suggestions?
