Scripting!

[bradders2010]

HELP!!! im half way through making my Full conversion and there is a couple of things bugging me! throughout the game you eventually turn the power on in the map. the map where the power switch is i can turn on the lights and thats works. but what about other maps because i go back into the previous maps where the lights arnt lit but i need a script where once the switch is pressed it turns them on no matter what map? PLEASE HELP
