Loop and lookup

Hi,

I have made an attempt at a sub that looks through Column A of a pivot and then attempts to match it to a pivot on another tab, if the value is there the selection turns green, if not, it turns red. My syntax or method is wrong however!

Can anyone offer suggestions?

Thanks
Seamus





Sub ASPAPHOENIXMATCH()

Range("A5").Select



Do Until ActiveCell = "Grand Total"
ActiveCell.Offset(1, 0).Select
With Selection

If(VLOOKUP(selection,'Phoenix Pivot'!A:A,1,0) = true then
Selection.Interior.Color = 65280

End If
Else
Selection.Interior.Color = 255
Loop




End Sub

Seamus, this should correct your syntax:

Sub ASPAPHOENIXMATCH()
Dim vResult As Variant

    Range("A5").Select

    Do Until ActiveCell = "Grand Total"
        ActiveCell.Offset(1, 0).Select
        With Selection
            
            vResult = Evaluate("VLOOKUP(""" & Selection.Value & """,'Phoenix Pivot'!A:A,1,0)")
            If Not IsError(vResult) Then
                Selection.Interior.Color = 65280
            End If
            
            .Interior.Color = 255
        End With
    Loop

End Sub

Note the double quotes around the Selection.Value.  You could use the WorksheetFunction.Vlooup as well, however I find using Evaluate a bit easier to remember and to validate as I'm coding it.

Setting the variant vResult = Evaluate(Vlookup) will not generate an error, as it stores the result (even an error message) into vResult.

The IsError() is used against the variant vResult to determine whether the VLookUp was successful or not.

Cheers,

Dave

PS - there are some color constants you can also use with

Selection.Interior.Color =

vbBlack
vbRed
vbGreen
vbYellow
vbBlue
vbMagenta
vbCyan
vbWhite


Cheers,
