Or what do you write when you only want numbers to be allowed nothing else?

Replies DefaultTo0 Posted at 11:11 am on Mar. 18, 2008 Put 'number' as the data type - this will serve for all basic needs. I believe that there is an input mask that you can use to specify only numbers.  I know that the letter 'L' means 'allow one letter'.  Unsure how to specify that it can be of any length though.
