Using "If cell contains" in VBA excel

Question

I'm trying to write a macro where if there is a cell with the word "TOTAL" then it will input a dash in the cell below it. For example:

In the case above, I would want a dash in cell F7 (note: there could be any number of columns, so it will always be row 7 but not always column F).

I'm currently using this code, but it's not working and I can't figure out why.

Dim celltxt As String
Range("C6").Select
Selection.End(xlToRight).Select
celltxt = Selection.Text
If InStr(1, celltext, "TOTAL") > 0 Then
Range("C7").Select
Selection.End(xlToRight).Select
Selection.Value = "-"
End If

Help would be appreciated. Hopefully I'm not doing something stupid.

Answer 1

Private Sub Workbook_SheetChange(ByVal Sh As Object, ByVal Target As Range)

If Not Intersect(Target, Range("C6:ZZ6")) Is Nothing Then

    If InStr(UCase(Target.Value), "TOTAL") > 0 Then
        Target.Offset(1, 0) = "-"
    End If

End If

End Sub

This will allow you to add columns dynamically and automatically insert a dash underneath any columns in the C row after 6 containing case insensitive "Total". Note: If you go past ZZ6, you will need to change the code, but this should get you where you need to go.

Answer 2

This will loop through all cells in a given range that you define ("RANGE TO SEARCH") and add dashes at the cell below using the Offset() method. As a best practice in VBA, you should never use the Select method.

Sub AddDashes()

Dim SrchRng As Range, cel As Range

Set SrchRng = Range("RANGE TO SEARCH")

For Each cel In SrchRng
    If InStr(1, cel.Value, "TOTAL") > 0 Then
        cel.Offset(1, 0).Value = "-"
    End If
Next cel

End Sub

This does the same, enhanced with CONTAINS:

Function SingleCellExtract(LookupValue As String, LookupRange As Range, ColumnNumber As Integer, Char As String)
Dim I As Long
Dim xRet As String
For I = 1 To LookupRange.Columns(1).Cells.Count
     If InStr(1, LookupRange.Cells(I, 1), LookupValue) > 0 Then
        If xRet = "" Then
            xRet = LookupRange.Cells(I, ColumnNumber) & Char
        Else
            xRet = xRet & "" & LookupRange.Cells(I, ColumnNumber) & Char
        End If
    End If
Next
SingleCellExtract = Left(xRet, Len(xRet) - 1)
End Function
