don't use /ad with dialog it is annoying just use /ad [text]
if you want it like i stated this is the way:

pawn Code:

CMD:ad(playerid,params[])
{
    new text,string[160],gname[MAX_PLAYER_NAME];
    GetPlayerName(playerid,gname,sizeof(gname));
    if(sscanf(params,"s[50]"text)) return SendClientMessage(playerid,-1, "(ERROR): /ad [ text ] " );
    format(string,sizeof(string),"ADVERTISEMENT[ %s ]: %s",gname,text);
    SendClientMessageToAll(COLORHERE,string);
    return 1;
}
