Hey @MK-p ,

Clear Value clears value as well as messages related to the field, can you try adding error message post clearing value as below.

var regex = /^(1[0-3]|[1-9])$/;
    
    if (!regex.match(newValue)) {
        g_form.clearValue('xxx'); 
        g_form.showFieldMsg('xxx', 'Please enter a number between 1 and 13.', 'error');
    }

@MK-p 

it's because it's going inside a loop.

you are validating the value with Regex and again setting it which in turns trigger client script

try this

var isUpdating = false; // Declare a flag

function onChange(control, oldValue, newValue, isLoading) {
    if (isLoading || isUpdating) {
        return; // Exit if the form is loading or if the script is already updating the field
    }

    var regex = /^(1[0-3]|[1-9])$/;

    if (!regex.test(newValue)) { // Use regex.test() instead of regex.match()
        g_form.showFieldMsg('xxx', 'Please enter a number between 1 and 13.', 'error');
        
        isUpdating = true; // Set the flag before updating the field
        g_form.setValue('xxx', 0); 
        isUpdating = false; // Reset the flag after updating the field
    }
}
