I recently made a macro to insert certain values on a spreadsheet into
another worksheet in the same workbook. My code is this.

Sub copy_1_Values_PasteSpecial()
Dim sourceRange As Range
Dim destrange As Range
Dim Lr As Long
Application.ScreenUpdating = False
Lr = LastRow(Sheets("Invoices")) + 1
Set sourceRange = Sheets("PO Form").Range("A44:G44")
Set destrange = Sheets("Invoices").Range("A" & Lr)
sourceRange.Copy
destrange.PasteSpecial xlPasteValues, , False, False
Application.CutCopyMode = False
Application.ScreenUpdating = True
End Sub

Function LastRow(sh As Worksheet)
On Error Resume Next
LastRow = sh.Cells.Find(What:="*", _
After:=sh.Range("A1"), _
Lookat:=xlPart, _
LookIn:=xlFormulas, _
SearchOrder:=xlByRows, _
SearchDirection:=xlPrevious, _
MatchCase:=False).Row
On Error GoTo 0
End Function


This formula worked great for the PO Form worksheet. I then wanted to
add an almost identical worksheet to the workbook and have it do the
same thing. I named it PO Form2 but I was unsuccessful in implementing
it. This was the code that I used.

Sub copy_1_Values_PasteSpecial()
Dim sourceRange As Range
Dim destrange As Range
Dim Lr As Long
Application.ScreenUpdating = False
Lr = LastRow(Sheets("Invoices")) + 1
Set sourceRange = Sheets("PO Form2").Range("A44:G44")
Set destrange = Sheets("Invoices").Range("A" & Lr)
sourceRange.Copy
destrange.PasteSpecial xlPasteValues, , False, False
Application.CutCopyMode = False
Application.ScreenUpdating = True
End Sub

Function LastRow(sh As Worksheet)
On Error Resume Next
LastRow = sh.Cells.Find(What:="*", _
After:=sh.Range("A1"), _
Lookat:=xlPart, _
LookIn:=xlFormulas, _
SearchOrder:=xlByRows, _
SearchDirection:=xlPrevious, _
MatchCase:=False).Row
On Error GoTo 0
End Function

An error came back saying Ambiguous name detected :
