Jim,
I suspect that you may misunderstand the IsDefined( ) function. That
function checks for the existence of a variable. Even if a variable
doesn't contain a value, if it is defined, IsDefined(varname) will return
true.
It sounds like you might want to check for contents of the variables you
are testing. Since they are form variables, I would suggest you use:
<CFIF Len(Trim(form.qty1)) AND Len(Trim(form.uc1))>
That will check if the variable has a value after trimming off any extra
spaces.
hth,
Kevin
