Listbox filter form onclick

Help, I have a form that i want to filter. I've got a table called filters that i want to load from a table called filters into a listbox.
(attached- please view) when the user clicks that row, i want that filter to be applied.

eventually, if i can figure this out, I would like an independent for to load with the listbox, then an onclick event loads the form with the filter pre applied.

Please help, i've completed this much (see attachment)

I just want to activate the filter in the listbox onclick. I just don't know how to do it. Please take a look.

thanks.
