[Logic_]

PHP код:

CMD:teles(playerid, params[]) 
{ 
    ShowPlayerDialog(playerid, 2, DIALOG_STYLE_LIST, "Teleports", "Abondoned Airport\nSan Ferrieno Airport\nLos Santos Airport\nLas Venturas Airport","Teleport","Cancel"); 
    return 1; 
} 


put this somewhere in your script, this shouldn't be under/ in any callbacks.

EDIT: +

PHP код:

public OnPlayerCommandText(playerid, cmdtext[]) 


remove this callback, no need of it.
