Interface Jumpbutton not working

[JGoode]

This is what I have in my interface:

ui_button ui_function, "Fire", 0, 5, 150,40, -TABID_1

This is what I have in my parameters:

glob_ui_button_ID = 0

if GLOB_UI_BUTTON_ID < 0 then
	parameters gs_ui_current_page = -GLOB_UI_BUTTON_ID
endif

Is there any reason this isn't working correctly?

This is in a Model View Options object too, if that makes any difference since it uses the old method of defining pages.
