Change to:

pawn Код:

#define Syntax(%0,%1) SendClientMessage(%0, 0xFFFF00FF, %1)
#define Error(%0,%1) SendClientMessage(%0, 0xFF0000FF, %1)

I accidentally used semicolon at the end. And look here:

pawn Код:

if(sscanf(params, "us[65]", toid, message)) return Syntax(playerid, "[a]dmin[m]essage", "[playerid] [message]");
if(sscanf(params, "s[80]", message)) return Syntax(playerid, "[a]dmin[m]essage", "[message]");

You're using "message", "message". The SendClientMessage function has 3 parameters and you're using 4.

Change to:

pawn Код:

if(sscanf(params, "us[65]", toid, message)) return Syntax(playerid, "[a]dmin[m]essage: [playerid] [message]");
if(sscanf(params, "s[80]", message)) return Syntax(playerid, "[a]dmin[m]essage: [message]");
