How do I shorten the length of my field and only allow numeric characters

[Cupcake]

I have a field on a catalog form. The field is requesting the last four digits of the SSN # or Personal ID #. Today the field is setup as a single line text field, but I want to do the following:

a) make the field size = 4

b) I only want to allow that field to have numeric characters

I want to ensure that when I shorten the field size that I am only shortening it for this variable.

Thanks,

Karen

I think you would need to run an onchange client script on the field to make sure that there are not more than 4 digits and they're all numbers.

Two things to do:

1. In the attributes field of the variable, add max_length=4
2. Create an onChange client script for the field with the following code:

function onChange(control, oldValue, newValue, isLoading, isTemplate) {

        if (isLoading || newValue == '') {

                  return;

        }

        var check = new RegExp('\d\d\d\d');

        if(!check.test(newValue)){

                  alert('Please enter a valid PIN or Last Four'); //The wording can be modified, of course.

                  control.value = oldValue;

        }

}

Joshua two things:

a) the max_length = 4 is working perfectly

b) I am getting a bad escapement error on the client script
