How do you go about totaling text fields on a form. I'm working on an expense report. I have dollar values (complete with decimal points) that the users enter into text fields and I have one "total" text field at the bottom of the form that I want to dynamically be updated with the total of all the other fields, if that is possible. Otherwise, I could just have them click a button to total the box. I need some script that will do this. Is there any out there already? (I'm sure there is, I've seen it!) Thanks in advance.
