How to validate numeric data?
I need to validate numeric data in a textbox. The entry needs to be 0,1,2,3,4
and nothing else. I'm having a hard time since no entry and zero appear to be the same thing but I do want the zero entered instead of leaving it blank.
I've tried inlist(0,1,2,3,4) but blank is as good as zero to this function.
Ideas?
