Gmod Gamemode Error

Hello Facepunch Users

I Have Just Made A Super Gamemode And I Tested It All Things Work Exsept The Spawnmenu,
It Comes Up With It But If I Say I Spawn A Car It Says “Unknown Command Gm_Spawncar” Or Somphin But If I Spawn A Weapon It Says “Unknown Command GM_GiveSwep”
You Get The Idear, Please Post If You Know Why But Dont Talk About Somphin Else.
SORRY I POSTED IN WRONG PLACE LAST TIME.
