Want option for Number field to contain only digits [RESOLVED]

Nevermind. I found the advice to use a numerical mask in a single line text field.

The Number field currently has three options: comma, decimal, or currency. Please add a fourth option: integer.

The Number field on my form must contain an ID number of 3 to 6 digits, numbers only, no comma or decimal. I don’t see a way to force that without an option of “integer” for the field format.
