For i = 0 To 10

Label1(0).Caption = 11 - i

Label1(1).Caption = 21 - i

Label1(2).Caption = 31 - i

Label1(3).Caption = 41 - i

If i = 0 Then

Shape10.FillColor = &HC0C0&

Shape1.FillColor = &HC0&

Shape2.FillColor = vbYellow

Shape5.FillColor = vbRed

Shape8.FillColor = vbRed

Shape11.FillColor = vbRed

Else

Shape12.FillColor = &H8000&

Shape2.FillColor = &HC0C0&

Shape3.FillColor = vbGreen

End If

tunda

Next i

For i = 10 To 20

Label1(0).Caption = 51 - i

Label1(1).Caption = 21 - i

Label1(2).Caption = 31 - i

Label1(3).Caption = 41 - i

If i = 10 Then

Shape5.FillColor = &HC0&

Shape3.FillColor = &H8000&

Shape2.FillColor = vbYellow

Shape4.FillColor = vbYellow

Else

Shape2.FillColor = &HC0C0&

Shape4.FillColor = &HC0C0&

Shape6.FillColor = vbGreen

End If

tunda

Next i

For i = 20 To 30

Label1(0).Caption = 51 - i

Label1(1).Caption = 61 - i

Label1(2).Caption = 31 - i

Label1(3).Caption = 41 - i

If i = 20 Then
