Hi there,

I want to know how to make the users put only numbers in the Zip Code field. Currently they can put "12365-5623" "abd2454" and so on.

Thankful.

Hi Jerome, it worked perfectly.

But I made some changes. In the documentation speak to use only [0-9] + but this causes special characters to be used or letters. The code only causes the first character to be a number from 0-9.

I used the following code: ^ [0-9] + $ and it works perfectly. Only numbers, no letters or special characters.

Very Thanks
