Many thanks go to Peter Brunone for your help, however... I updated the code, but things still don't "add up" (okay, bad joke). Whichever box I enter a number into first is never added to the total... unless I go back and retype that number once addition has begun. Also, the script seems to be completely ignored by Netscape 4.7. I tried setting an "initial value" of "0" for each form element, hoping that a change from zero would trigger a response from the JavaScript. It did not. The newer version of the form can be tested at <http://www.city.newport-beach.ca.us/nbpl/literacyform04.htm> http://www.city.newport-beach.ca.us/nbpl/literacyform04.htm. Thanks again for your expertise and time! Sincerely, Thomas McCoy (amateur JS programmer) -------------- next part -------------- An HTML attachment was scrubbed...
