How to duplicate option explicit VBA code excel 2010

I have used the information from another post but this is a new type of enquiry.

I have used the above and it works perfectly!
My issue is I am creating a coin book and would like to run the same code for more than one cell being updated (different denominations) and with a chosen description as well.
I've used the following modification for the singular cell to achieve this for 5 cent bags,

Option Explicit

Private Sub Worksheet_Calculate()

Dim iLastRow As Long
Dim tsi As Worksheet
Dim mws As Worksheet

Set tsi = ThisWorkbook.Sheets("Timestamp Info")
tsi.Range("A1") = "Description"
tsi.Range("B1") = "New Value"
tsi.Range("C1") = "Date/Time Changed"

iLastRow = tsi.Cells(tsi.Rows.Count, 1).End(xlUp).Row

Set mws = ThisWorkbook.Sheets("Sheet1")

If mws.Range("B1").Value <> tsi.Cells(iLastRow, 1).Value Then
tsi.Cells(iLastRow + 1, 1) = "changed total 5 cent bags"
tsi.Cells(iLastRow + 1, 3) = Format(Now(), "dd/mm/yyyy hh:nn:ss")
tsi.Cells(iLastRow + 1, 2) = mws.Range("B1").Value
End If

End Sub

This runs perfectly for what I wish to do however when I try to duplicate the code, only the second code runs (10 cent bags) even when the 1st codes cell is the one that has been altered.

Option Explicit

Private Sub Worksheet_Calculate()

Dim iLastRow As Long
Dim tsi As Worksheet
Dim mws As Worksheet

Set tsi = ThisWorkbook.Sheets("Timestamp Info")
tsi.Range("A1") = "Description"
tsi.Range("B1") = "New Value"
tsi.Range("C1") = "Date/Time Changed"

iLastRow = tsi.Cells(tsi.Rows.Count, 1).End(xlUp).Row

Set mws = ThisWorkbook.Sheets("Sheet1")

If mws.Range("B1").Value <> tsi.Cells(iLastRow, 1).Value Then
tsi.Cells(iLastRow + 1, 1) = "changed total 5 cent bags"
tsi.Cells(iLastRow + 1, 3) = Format(Now(), "dd/mm/yyyy hh:nn:ss")
tsi.Cells(iLastRow + 1, 2) = mws.Range("B1").Value
End If
If mws.Range("B2").Value <> tsi.Cells(iLastRow, 1).Value Then
tsi.Cells(iLastRow2 + 1, 1) = "changed total 10 cent bags"
tsi.Cells(iLastRow2 + 1, 3) = Format(Now(), "dd/mm/yyyy hh:nn:ss")
tsi.Cells(iLastRow2 + 1, 2) = mws.Range("B2").Value
End If

End Sub

Any help at all would be appreciated, happy to give more info if needed.
