Hi Hemanth,

Please try,

function onSubmit() {

    if(g_form.getValue('field_name').length > 15){
		g_form.showFieldMsg('Enter less than 15 characters ', 'error', true);
		return false;
	}
}

Mark Correct and Helpful if it helps.

Hi Yousaf,

Thanks for the script,

Is it possible to calculate first name field and last name field and show the error if it is more than 15 characters?

Thanks in Advance!!

hemanth you mean the total of both fields?

first name + last name should not be greater than 15?

Yes first name + last name should not be greater than 15?
