How to allow prop spawn and the Q menu?

I know the answer will be really simple, but I spent a while trying to find out and I have looked all over for it, and I still don’t know. Like it says in the title, I want to enable the spawn menu and prop spawning in general; but the error I’m getting is “Unknown Command: ‘gm_spawn’”. Any help would be welcomed!

Thanks in advance :slight_smile:

Wich gamemode are you using?

This a gamemode I am currently making.

Derive your gamemode from sandbox, not base gamemode.

When I do that I get this error when “undo-ing” a prop.

And the spawn menu still does not open.
