You could definitely clean this script up a bit
The following code:
PHP Code:
Feedback_Test_Window2.hide();
Feedback_Test_CheckBox1.hide();
Feedback_Test_Text1.hide();
Feedback_Test_Text2.hide();
Feedback_Test_Text3.hide();
Feedback_Test_Button1.hide();
Feedback_Test_Button2.hide();
Should be put in its own function since I can see it occur twice.
Also the use of 2 server strings isn't needed since you can just tally the yes and no votes together. The overall flow of the program isn't too shabby. Im not to familiar with GS2 so I can't really make any more comments.
