WHY Chat? you are checking the ssanf params there so

pawn Код:

""chat" /gotopos [playerid]");

should be

pawn Код:

"/gotopos [playerid]");

You used a double quote and chat...
also

pawn Код:

SendClientMessage(playerid,-1,""chat""COL_GREY" You cannot use this command");

should be

pawn Код:

SendClientMessage(playerid, COL_GREY,"You cannot use this command");//-1 is a random color and after that you use COL_GREY be sure this is defined or you must use code like 0xFFFFFFAA (White)
