Missing map error on Gmod server?

Hi

I am currently putting together Garry’s Mod Surf server which will soon go onto a box. I am currently adding maps hoping FastDL works etc. I downloaded some maps for the server of a website and placed the .bsp files in the maps folder on the server. When I try join, it comes up with missing map. I was wondering how to make it download when I join and for other players who join

Cheers

— Nevermind, worked it out ----
