No weapon hud

Hey i started my gmod up yesterday and found that when i pressed 1,2 or 3 to select a weapon there was no hud when i asked around someone told me it was because i played on Mr greens zombie survival but i dont know how to fix it, any help please?

Tried typing “cl_drawhud 1” in the console?

No, I get what he means, the little yellow ICONS don’t popup when he presses 1,2,3,4,5 etc.

This is happening to myself aswell.
