Hi i am quite new to both php and concrete 5, but love them both... i have put together a simple html form where a user can input some simple dimentions. The form then posts the information to a seperate php file which processes the dimentions, does a complicated calculation and displays an estimate price .

How would i go about implementing this form and process into concrete 5?

It is very simple to create the form, but i can not include php script into the html editor....

Thanks in advance for any assistance.
