Thanks for all the help everyone, but I couldn't get either Drumstix's or GM9's options to work, but in the good news i figured out a way other than those ways ...
I added 2 buttons to the template file both "new" buttons press the default add button, one of the custom buttons also /hide_window also. The reason I added the 2nd custom button instead of using the default add button was because my custom "add and close" button was always visible and the default "add" button wasn't. SO I added a 2nd custom button so it was always visible like my first custom button but behaves like the default add button.
The words overflow a bit on the first button for right now because this is just a temporary fix until i recode / re-skin this window in the future.
Thanks again for all the help, i just couldn't get it to work.
