VBA loop selection.find - excel

Question

I want to loop or find multiple value in another sheets. My code doesn't work even after I do..loop the code.
For i = 1 To lastrowBAU
Worksheets(fname).Range("A1:A" & lastrowsheet).Select
Do Until Cell Is Nothing
Set Cell = Selection.find(What:=ThisWorkbook.Worksheets("BAU").Range("A" & i).Value, After:=ActiveCell, LookIn:=xlFormulas, _
LookAt:=xlPart, SearchOrder:=xlByRows, _
MatchCase:=False)
If Not Cell Is Nothing Then
Cell.Activate
ActiveCell.Copy
ActiveCell.Insert Shift:=xlShiftDown
ActiveCell.Offset(1, 0).Select
Selection.Replace What:=ThisWorkbook.Worksheets("BAU").Range("A" & i).Value, _
replacement:=ThisWorkbook.Worksheets("BAU").Range("B" & i).Value, _
LookAt:=xlPart, SearchOrder:=xlByRows, MatchCase:=False
Set Cell = Worksheets(fname).Range("A1:A" & lastrowsheet).FindNext(Cell)
End If
Loop
Next i

You need to set the cell before entering the loop
Set cell = rngSrc.Find(sA, LookIn:=xlFormulas, LookAt:=xlPart, _
After:=rngSrc.Cells(rngSrc.Cells.Count), SearchOrder:=xlByRows, MatchCase:=False)
If Not cell Is Nothing Then
however you also need to avoid an endless loop by checking if the search has returned to the first one found.
Option Explicit
Sub macro1()
Dim ws As Worksheet, wsBAU As Worksheet
Dim cell As Range, rngSrc As Range
Dim fname As String, lastrow As Long, lastrowBAU As Long
Dim i As Long, n As Long, first As String
Dim sA As String, sB As String
fname = "Sheet1"
With ThisWorkbook
Set ws = .Sheets(fname)
Set wsBAU = .Sheets("BAU")
End With
With ws
lastrow = .Cells(.Rows.Count, "A").End(xlUp).Row
Set rngSrc = .Range("A1:A" & lastrow)
End With
With wsBAU
lastrowBAU = .Cells(.Rows.Count, "A").End(xlUp).Row
End With
With ws
lastrow = .Cells(.Rows.Count, "A").End(xlUp).Row
Set rngSrc = .Range("A1:A" & lastrow)
End With
' search and replace
Application.ScreenUpdating = False
For i = 1 To lastrowBAU
sA = wsBAU.Cells(i, "A")
sB = wsBAU.Cells(i, "B")
Set cell = rngSrc.Find(sA, LookIn:=xlFormulas, LookAt:=xlPart, _
After:=rngSrc.Cells(rngSrc.Cells.Count), SearchOrder:=xlByRows, MatchCase:=False)
If Not cell Is Nothing Then
first = cell.Address
Do
' insert cell above
cell.Insert xlDown
cell.Offset(-1).Value2 = cell.Value2
cell.Value2 = Replace(cell.Value2, sA, sB)
' expand search range
n = n + 1
Set rngSrc = ws.Range("A1:A" & lastrow + n)
' find next
Set cell = rngSrc.FindNext(cell)
Loop While cell.Address <> first
End If
Next
Application.ScreenUpdating = True
MsgBox n & " replacements", vbInformation
