Hey, Me again..

Ok I have had an idea for a map for Half Life 2 deathmatch.. and so far its only just a big room like a kill box with a few walk ways and a teleport.. it is compiling fine and everything works when i run it as a normal HL2 map..
But when i add an info_player_deathmatch in beside my player start and compile its not working?
It opens DM and everything and in the console window it does all its work like in H-Life but then just when you think its all going to work..

Is what happens in the console.. anyone any idea why this is happening?

Thanks for your time in reading.
