Translate 2007 Conditional Formatting in 97-2003

Hi,

I've created the below VBA in Excel 2007. I don't have a computer with 97-2003 to do testing on it, so I'm hoping someone can help me translate it to be backwards compatible. Thanks.

    With Worksheets(mainWS).Range(Worksheets(mainWS).Cells(firstSelectionMenu, upgradeSelectionCol), Worksheets(mainWS).Cells(lastSelectionMenu, upgradeSelectionCol))
        .Validation.Add Type:=xlValidateList, AlertStyle:=xlValidAlertStop, Operator:=xlBetween, Formula1:="=$A$1:$A$" & FinalRow
        .FormatConditions.Add Type:=xlExpression, Formula1:="=LEFT(D11,7)<>""Upgrade"""
        .FormatConditions(Selection.FormatConditions.Count).SetFirstPriority
        .FormatConditions(1).Interior.ColorIndex = 1
        .FormatConditions(1).StopIfTrue = True
    End With
