Modding main menu (onleft/right) help

Im modding the main home menu in the includes file to trigger some hidden buttons.

In the main menu (id=300)
Works fine & triggers button 7013

But
Does'nt work, as a test i even deleted <onleft>300</onleft> & <onright>300</onright & i can still navigate left/right!

Any help please, i don't know what is still navigating the main menu.

Hope that makes sense

Thanks
