You didn't replace [color] with your desired colour. Also, that snippet has flawed logic. It'll fail if the player HAS more than 1000 score.

pawn Код:

if(GetPlayerScore(playerid) <= 1000) return SendClientMessage(playerid, REPLACE_ME_WITH_YOUR_COLOR,  "You have to get 1000 score before you can use this command");

PS: You should use [pawn] shortcode instead of [php]
