VBA nested IF in excel

I am relatively new to VBA. I am trying to write a code for nested IFs in VBA. I have the following code, yet the output is wrong. How can I make the nested if function work?

    Private Sub CommandButton1_Click()


  If Range("H2") = 1 Then
     Range("X3") = "$CT$10:$CT$150"

       If Range("H2") = 2 Then
     Range("X3") = "$CZ$10:$CZ$150"

      If Range("H2") = 3 Then
     Range("X3") = "$DF$10:$DF$150"

     If Range("H2") = 4 Then
     Range("X3") = "$DL$10:$DL$150"

     If Range("H2") = 5 Then
     Range("X3") = "$DR$10:$DR$150"

     If Range("H2") = 6 Then
     Range("X3") = "$DX$10:$DX$150"

     If Range("H2") = 7 Then
     Range("X3") = "$ED$10:$ED$150"

     If Range("H2") = 8 Then
     Range("X3") = "$EJ$10:$EJ$150"

     If Range("H2") = 9 Then
     Range("X3") = "$EP$10:$EP$150"

     If Range("H2") = 10 Then
     Range("X3") = "$EV$10:$EV$150"

     If Range("H2") = 11 Then
     Range("X3") = "$FB$10:$FH$150"

     If Range("H2") = 12 Then
     Range("X3") = "$FH$10:$FH$150"



  End If
  End If
  End If
  End If
  End If
  End If
  End If
  End If
  End If
  End If
  End If
  End If



End Sub

The code somehow works only if H2 = 1. Otherwise it does not work.
