I have no clue what I'm doing wrong, so feel free to beat me over the head with something obvious.
I am not sure what you mean ....but to add script to an object, make sure that the object has focus and then in the script editor choose the event that you want the code to run on. Then choose the language that you want to use. Now add your code.
You can send your form firstname.lastname@example.org and I can check it out.
Once I add it the code also appears when FormCalc is selected and "Click" has an asterix appended to it: "Click*"
