cant run l4d2 map

im working on a map with my friend. and i made the first building. i tryed to run the map. and after the compiler nothing happens. can u help me. i cant copy and paste the compile. it wont let me highlight it.

Open the game, then in console type, “map (Map name here)”

On the compile log click on “copy to clipboard”.

And for gods sake, use proper punctuation and grammar.
