I still wonder why people tend to use sscanf for one parameter commands when you can just params.

pawn Code:

CMD:test(playerid, params[])
{
    new str[128];
    format(str,sizeof(str),"%s",params);
    SendClientMessage(playerid,color,str);
    return 1;
}

Will work just effectively as using sscanf, same can be applied to the command you used.
