Ok, when after making my map with hammer editor,I compile it then it goes into the counter strike menu and does nothing. Then once i open the console it says, "Host_EndGame: Map coordinate extents are too large!!" HOW do i fix this to make my map work?,
Uhm. Your map is extending over the outside of the grid. You may have a broken brush somewhere that's spilling over outside of the coordinate space. Make sure you fix any errors in the map, and then recompile.
