Form totals without having to submit form?
Hey everyone. I have a project I'd like to create, but need some help with (Note, I am a newbie with PHP).
I want to create a carbon footprint calculator as part of a school project. The equations will be created using PHP equations and a form for user input values.
I would like to know if (and how) the totals for the users input can be displayed on the screen, without the user having to submit the form. Thanks in advance for your help.
