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');
    }

Hi @MK-p ,

This is happening because it is your code is executing multiple time on onChange.

Either you can clear the filed or terminate the loop post error.

you can do like below.

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

Hi @MK-p ,

Put clear message before field message.
