Subject: How to test for a number
How do you make an If check to check to see if a user has entered a
number and not a letter?
I can stop it from doing a divide by 0 doing this:
on mouseUp
put field"num1" into tAdd
put field"num2" into tAdd2
if tAdd2 is 0 then
answer "You can't divide by 0"
else
put tAdd/tAdd2 into field"sum"
end if
end mouseUp
Thanks
Kevin
