Regular Expression - Expressions allow you to filter the data you allow the user to input in the field. Regex can be rather complicated so ask for assistance if you have trouble getting this to work properly. For example, the following regex would only accept a number in the range of 1 to 50: ^([1-9]$|[1-4][0-9]|50)$

The following regex would only accept a 7 or 8 digit number:
^([0-9]{7,8})$
