Users Cant Spawn Lights, Unknown Convar???

Hi, I have started a gmod server and i have it more less set up to how i want it but for some reason me as the owner is the only person who can spawn lights.
i am using Evolve and when i try to change the number of light player can spawn it says Unknown Convar. I have it in the server.cfg but its still not working,
“sbox_maxprops” “150”
“sbox_maxragdolls” “5”
“sbox_maxnpcs” “5”
“sbox_maxballoons” “10”
“sbox_maxeffects” “5”
“sbox_maxdynamite” “5”
“sbox_maxlamps” “20”
“sbox_maxlights” “20”
“sbox_maxthrusters” “10”
“sbox_maxwheels” “8”
“sbox_maxhoverballs” “6”
“sbox_maxvehicles” “6”
“sbox_maxbuttons” “20”
“sbox_maxemitters” “5”
“sbox_maxspawners” “3”
“sbox_maxturrets” “4”

I have no idea what is wrong, prob something silly but im stumped.

Any Ideas???

Thanks Alot
