Validation rule- Can't begin with 5

[jamphan]

I need to have a validation rule on a form that will not allow users to input any number that begins with a 5. The field is a text field because it requires 16 digits for each number. Is there a way I can stop the user from entering any number that starts with 5? Thanks for the help.

Insert a validation rule for that field in your table as follows:

Left([Field],1)<>5
