You use else if without an if stament before. It should be:

pawn Код:

if(playerDB[playerid][plead] == LEAD_FARAI) 
{
    format(wel,sizeof(wel),"My text",dirname); 
    ShowPlayerDialog(playerid,6698,DIALOG_STYLE_MSGBOX,"{FFFFFF}Naudinga informacija",wel,"Uћdaryti",""); 
}
else if(playerDB[playerid][plead] == LEAD_MEDIKAI) SendClientMessage(id,Zalia,"Jūs kviečiamas pas medikus. Dėl darbo priėmimo.");
