Form Calculation

This is a very basic JavaScript code to calculate the value of form elements.

It can become quite useful when wanting to add items up on the fly if you prefer not to use ajax or you do not have a server side scripting language available.

    Hey,

    Great code you have. I was trying to get it working with other form fields that dont get added up but it seems to break your code.

    Is there a way I can add additional fields... like for a name, to the form without breaking the calculation?

    Thank you for your time.

    Robert

    I tried your code but my total is always "NaN"

      in the end of for (var f = 0; f < userInputs.length; f++){

      add fields[f] = 0;
