I did everything, that Wiki said, but when I start my map, it comes with error cannot find maps/nazi_zombie_test_fx. When I went to check the maps folder, it wasnt there. There was sumpf, factory, prototype, asylum, but no test. Any help with this?

That file has nothing to do with UGX Easy FX and is not controlled or affected by my script in any way. Whatever you did to create/generate your map's scripts did not place all the correct files. To get it to stop looking for that fx file, open your map's mapname.gsc and remove the line that calls the fx file near the start of mapname.gsc.
