Couldn't include file 'shared.lua' error.

[irnez]

Heya guys.

I just recently started learning lua and stuff and i followed some random persons lua guide to make a custom gamemode. and im stumped. i got an error after trying my gamemode. Could you guys help me out?
its a custom team deathmatch gamemode. And if you guys find the problem, could you point a way i could make it so that when people join they are automatically spectator and have to choose a team?

shared.lua
