Please don't think we can read minds or do astral projections to see your monitor. If you need help, the least you could do is to explain your problem in such a way, that the users of CP can understand it. Otherwise, nobody will be able to help you.

You say you are trying, but show no evidence of it. You can use Char.IsNumeric and Char.IsControl in the key down event of a textbox to allow only numbers. You can then use int.TryParse to see if the number that you end up with is not in your range, and erase it if it is.
