Need help with this code involved array

[GoDxNero]

Ok i created a mini-game which involved throwing object. There are 5 objects(TImage). If I press on 'g' then if object 1 not throwed yet then it will be throw, if object 1 is throwed then object 2 will be throw and so on. When it reach certain Top.Position it will disappear and count as not throwed. Here is my code :

shot : Array[1..5] of TImage;

procedure TForm1.FormCreate(Sender: TObject);
begin
  for sh := 1 to 5 do
  shot[sh] := TImage.Create(Self);
  with shot[sh] do
  begin
    Parent := Self;
    Top    := 450;
    Left   := 250;
    Width  := 20;
    Height := 20;
    Visible := False;
    Picture.loadfromFile('Item1.jpg');
  end;
end;

procedure TForm1.FormKeyPress(Sender: TObject; var Key: char);
begin
  if (key = 'g') then
  begin
    if shot[1].Visible = False then
    shot[1].Visible := True
    else if shot[2].Visible = False then
    shot[2].Visible := True
    else if shot[3].Visible = False then
    shot[3].Visible := True
    else if shot[4].Visible = False then
    shot[4].Visible := True
    else if shot[5].Visible = False then
    shot[5].Visible := True;
  end;
end;

procedure TForm1.Timer1Timer(Sender: TObject);
begin
for sh := 1 to 5 do
  if shot[sh].Visible = True then
  shot[sh].Top := Shot[sh].Top - quickness - speed;
  if Shot[sh].Top < 80 then
  miss;
end;

procedure TForm1.miss;
begin
  for sh := 1 to 5 do
  if Shot[sh].Top < 80 then
  begin
    Shot[sh].Visible := False;
    Shot[sh].Top := 450;
  end;
end;

My probleem :
I cant throw more than 1 at a time .
When I throwed 1, I have to press 4 more times and object 1 have to be invisible else it wont throw


EDIT : Probleem solve. I have to start a begin and end for each loop  ;
