denno020 Posted March 15, 2013 Share Posted March 15, 2013 Just so you know, jQuery is javascript, just written in a nice way. you'll basically want to grab the values for the two text boxes, similar to this (using jQuery): var firstBox = $('#first_text_box').val() var secondBox = $('#second_text_box').val() Then you'll use a simple if statement to compare the values, and perform some action (alert) if the second is greater than the first if(secondBox > firstBox){ alert("Some message"); } Hopefully that'll get you started.
