When i run my gamemode, it says that it can't load, and neither of the frames show up.

I have no idea what the problem is.

It says there's a problem at line 89, which is the function thing and to be honest, i don't know what the function is supposed to do...

Please help, avwos.

firstperson.DoClick = function() on line 89. Swap the : for a .
