Limit Negative Numbers in UDF field.

Content

Hi,

I am looking to limit the characters of a UDF field to 2 digit Integer only and also limit negative numbers in a User Defined Form in Taleo Onboarding. I changed the Input Mask in the UDF Config to '99' and 'Save Literals' to Y, however while testing we noticed that we are still able to enter negative numbers in the field. Please can you let me know as to why this may occur and what should I change to make it just limit to positive 2 digit integer. Appreciate your inputs.
