I have been working on a custom List for a client. The idea is that a user will fill out a list and for each new row they add €3 will be added to their total. Is this possible using something like http://www.gravityhelp.com/documentation/index.php?title=Gform_column_input&oldid=1081 but instead of using a drop down change it to a product? Any help on this would be great thanks
