Script That changes Fog Distance?

Well, I'm making a game, and it's REALLY annoying to have to deal with fog while I'm working and I just want it to turn on when I join the game, if anyone could tell me a script that I could just put into lighting or something that would change the FogEnd distance to 180, that would be great.

What I tried was:

script.Parent.FogEnd = 180

in the script but it didn't work ;-;
