Ok, that makes good sense. Here is a code to use. You'll need to customize where the variables are initialized.
Public Sub MSmithson()
Dim strWS As String
Dim dblLastRow As Double
Dim intC1 As Integer
Dim intC2 As Integer
Dim intC3 As Integer
Dim intR1 As Integer
Dim i As Integer
'Initialize variables.
strWS = "Your Sheet Name"
intC1 = 1 'Enter the column number of Retained Notes (A = 1, B = 2, etc.)
intC2 = 2 'Enter the column number of Frozen Notes
intC3 = 3 'Enter the column number of Combined Notes
intR1 = 2 'Enter the row you want to start combining on.
With Sheets(strWS)
dblLastRow = WorksheetFunction.Max(.Cells(Rows.Count, intC1).End(xlUp).Row, .Cells(Rows.Count, intC2).End(xlUp).Row)
For i = 2 To dblLastRow
.Cells(i, intC3).Value = .Cells(i, intC1).Value & " " & .Cells(i, intC2).Value
Next i
End With
End Sub
