My code is wrong?

[Tarqs]

I have this code but it only pastes against the first matching row and not all matching rows, my code assumes the item i am trying to match is unique!

Any help much appreciated

Option Explicit
Sub ReportMatcher()
    Dim wsDest As Worksheet
    Dim wsSource As Worksheet
    Dim rngDest As Range
    Dim rngSource As Range
    Dim rng As Range
    Dim rowMatch As Variant
 
    Set wsDest = ActiveSheet
 
    If Not Application.Dialogs(xlDialogActivate).Show Then
        Exit Sub
    End If
 
    Application.ScreenUpdating = False
 
    Set wsSource = ActiveSheet
 
    With wsDest
        Set rngDest = .Range("D:D")
    End With
 
    With wsSource
        Set rngSource = .Range("A2", .Cells(.Rows.Count, 1).End(xlUp))
    End With
 
    For Each rng In rngSource.Cells
        If Len(rng.Value) > 0 Then
            rowMatch = Application.Match(rng.Value, rngDest, 0)
 
            If IsNumeric(rowMatch) Then
 
                wsDest.Range("T" & rowMatch).Value = wsSource.Range("B" & rng.Row).Value
                wsDest.Range("U" & rowMatch).Value = wsSource.Range("D" & rng.Row).Value
            End If
        End If
    Next rng
    Application.ScreenUpdating = True
 
    MsgBox "Order Numbers Added", vbInformation
End Sub
