Hi @Ria
You can utilize onchange Client script on mobile number field to validate if entered value matches 10 digits including only one "+" sign.
function onChange(control, oldValue, newValue, isLoading, isTemplate) {
if (isLoading || newValue === '') {
return;
}
// Get the mobile phone value
var phone = g_form.getValue('u_mobile_number');
// Define regex: '+' required at start, followed by exactly 10 digits
var regex = /^\+\d{10}$/;
// Validate
if (phone && !regex.test(phone)) {
g_form.showFieldMsg('u_mobile_number', 'Please enter a valid mobile number (+ followed by exactly 10 digits).', 'error');
} else {
g_form.hideFieldMsg('u_mobile_number'); // Hide error if valid
}
}
