in your image nothing is made any clearer unfortunately. The $_GET is to get the information ajax sends, presumably- through a GET pass.
You need to look at the return value of the script (Does it return a succesfull message) and at how your ajax is supposed to handle the result.
As I cannot see you ajax (No sorry, I do not open .zip files on the internet; if you want me to read specific pieces of code: get the relevant pieces, and paste them here in
or [code] BB tags) it is not possible to see how the return is supposed to be handled.
A clear way to test where things go belly-up is by inserting alert() commands for key-variables in key locations in your java handling functions.
