I clearly suggested to use "isnum", it's even marked. Just because I didn't directly apply it to the code, doesn't discredit the fact that I didn't offer the solution.
Anyhow, I have a class to go to and I'm not going to sit here and argue this with you. I know what my intentions were. If you want to take them out of context and twist them around, then that is your problem to deal with. The OP has already been answered and this has strayed off topic enough. Adios!
