I followed Harrybo's instructions all the way through, when I go into the map it says:

Server script compile error
unknown function

Please help! Just saying I'm relatively new to making zombie maps, and by that I mean this is my first time using anything that wasn't provided in the mod tools.

Type 'developer 1' in console. type 'devmap mapname' in console. press SHIFT + ~ and read the line that gives the "unknown function"

I managed to fix the error, it was an error with the Teleporter code so I used a different thread to fix that, but now when I try to play the map it loads fully, but when the loading bar goes away, it just goes to a plain black screen with the WaW main menu cursor on it, I can't move the cursor around nor can I open the menu.
