Variable must contain 12 numeric characters and not allowed single space in variable regex

For example there are given only 4 spaces or 12 spaces on that time also not allowed

Hi @mani55 

Try with this:

^\d{12}$

Hi @mani55,

I'm not sure that the regex can physically stop a user from being able to type a space, however the OOTB number regex will produce an error message if any non-number characters are entered.

As an alternative approach, you could create an onChange client catalog script that will notify the user if they have not entered a specific minimum number of characters. For example:

Below is the script I used:

function onChange(control, oldValue, newValue, isLoading) {
    if (isLoading || newValue === '') {
        return;
    }
    var minLength = 12; // Set your minimum character requirement here

    if (newValue.length < minLength) {
        g_form.showFieldMsg('your_variable_name', "Input must be at least " + minLength + " characters long.", 'error');
    } else {
        g_form.hideFieldMsg('your_variable_name'); // Clears the error once they type enough characters
    }
}

If you haven't already, you can also set the maximum number of characters that can be entered by adding max_length=12 to the variable attribute to stop users from being able to enter too many characters.
