Null mother... :(

I have some code that I want to run when the user trashes an object. I have the code (below) but when I preform the action, the Whats_Sound() proc causes a runtime error. Do you have any suggestions?

obj/objects
    proc
        Trash()
            if(src.loc == src.norm_loc)
                src.loc = usr.loc
                src.icon_state = "trashed"
                usr.score += 1
                usr.cash += 2
                var/mob/mom/M
                M.Whats_Sound()


runtime error: Cannot execute null.Whats Sound().
proc name: Trash (/obj/objects/proc/Trash)
source file: objects.dm,37
usr: Start Game (/mob/player)
src: the cds (/obj/objects/cds)
call stack:
the cds (/obj/objects/cds): Trash()

If its a proc then you dont need.

M.What_Sound()

just use What_Sound()

runtime error: Cannot execute null.Whats Sound().
proc name: Trash (/obj/objects/proc/Trash)
source file: objects.dm,37
usr: Start Game (/mob/player)

Usually when you get this sort of error, it means that you've got an object variable that you didn't assign to anything, which is precisely the case here with M--it's like you wrote out a little sticky-note label to identify something, but didn't stick it on anything. If you want to create a new mob/mom, you'd just assign M to new() (you've already declared M's type), or if you wanted to assign it to an existing mob, you'd simply assign it to an existing reference.

It's located in mob/mom though. The Trash proc is located in obj/objects.

Leftly, for fixing my proble, that's why I replied to him. But thanks, to you, for trying. :)
