No seriously, show us the code in those files so we can fix it.

In order:
Table doesnt have the index thats searched for.
Wrap the entity in ValidEntity there.
GetFuel doesnt exist.
gatekeeper module. Get it and install it.

I have got Gateskeeper module.

Did you do ‘require( “gatekeeper” )’

EDIT: its the gatekeeper module, its outdated and not working but when ever i get the updated one of the svn i get a steamid error.

put this in your server.cfg
