macros can't see a worksheet - 'runtime error 9' - excel

Question

I have 2 sheets and 1 macros that pastes values from one to another. The macros is working. I copied it and changed it a bit. But it can't run -
'run time error 9'
which is visibility issue.
All sheets are in same excel file.
original macros code, it works:
Sub original()
For j = 18 To 28
Worksheets("Express_vnzp").Select
srok = Cells(26, j).Value
stav = Cells(31, j).Value
komis = Cells(28, j).Value
stavka_privlech = Cells(29, j).Value
For i = 10 To 12
PD = Cells(i, 17).Value
Worksheets("Ðàñ÷åòû").Select
Cells(3, 2).Value = stav
Cells(4, 2).Value = srok
Cells(5, 2).Value = komis
Cells(7, 2).Value = stavka_privlech
Cells(15, 2).Value = PD
marzha2 = Cells(23, 2).Value
Worksheets("Express_vnzp").Select
Cells(i, j).Value = marzha2
Next
Next
End Sub
I copied and changed i,j - not working.
Sub erj()
For j = 3 To 4
Worksheets("creditcard").Select
srok = Cells(26, j).Value
stav = Cells(31, j).Value
komis = Cells(28, j).Value
stavka_privlech = Cells(29, j).Value
For i = 5 To 6
PD = Cells(i, 17).Value
Worksheets("ras").Select
Cells(3, 2).Value = stav
Cells(4, 2).Value = srok
Cells(5, 2).Value = komis
Cells(7, 2).Value = stavka_privlech
Cells(15, 2).Value = PD
marzha2 = Cells(23, 2).Value
Worksheets("creditcard").Select
Cells(i, j).Value = marzha2
Next
Next
End Sub
gives 'runtime error', its visibility issue.
