I scripted this /me command but it seems it has one error, can anyone fix it up?

Код:

CMD:me(playerid, params[])
{
	if(isnull(params)) return SendClientMessage(playerid, 0xFF0000FF, "SYNTAX: /me [action]");
	new string[128];
	format(string, sizeof(string), "* %s %s ", GetPlayerName(playerid), params);
	ProxDetector(30.0, playerid, string, 0xFF0000FF);
	return 1;
}

The error below:
C:\Users\homie\Desktop\script\gamemodes\Untitled.p wn(47) : warning 202: number of arguments does not match definition
