Hello.
Next time please place your code into [.pawn][./pawn] tags (without dots '.').

First at all, you must declare 'Pickup' array size. For your code, you should paste this:

pawn Код:

new Pickup[1];

instead of

pawn Код:

new Pickup[];

2nd thing.

pawn Код:

forward Pickupop;

instead of

pawn Код:

forward Pickup;

Why you're forwarding something for variable, not for public, eh?
You've done this script very chaotically.

Next thing:

pawn Код:

public Dialog_BuyRepaired(playerid, response, listitem);
{
    if(pickupid == pickups[0][mrepair])
    {
    
    if(GetPlayerMoneyA(playerid) < 500)
    {
    SendClientMessage(playerid,0xD9E916FF,"* Jбrműved megjavнtva (500$)) !");
    return 1;
    }

    new vehicleid = GetPlayerVehicleID(playerid);
    SetVehicleHealth(vehicleid,1000.0);
    return 1;
}
}

Forget closing } at the very end??

That should be all.
