CalcBuilder Forum

Hello,
you can add a button next to calculate one, but not sure what are you trying to get with Submit action. If fact, calculate button is a Submit button (although it's made through a hidden request). The action where the form is calling is your calculator code, so you can handle the fields as you where coding the action file using the php variables that are already 'collected'.
Remember you can insert any valid php inside the calculator code.

Hope this helps,
