Jason, my mistake. When I say "highlight", I actually meant "select". I want
to select all cells with lookup formulas so that I can use the Format
Cells-Protection-Locked option to protect the cells. Your macro works
beautifully to hightlight (fill background color) the lookup cells, I will
keep it in my notebook. Can you also modify it to let it "select" the cells?
Thanks!

Try this macro:

Option Explicit
Sub FindLookup()
Dim FormulaRng As Range
Dim FormulaCell As Range
Dim sFormula As String

On Error GoTo NoFormulas
Set FormulaRng = ActiveSheet.Cells. _
SpecialCells(xlCellTypeFormulas)
On Error GoTo 0

For Each FormulaCell In FormulaRng
With FormulaCell
sFormula = LCase(.Formula)
If InStr(sFormula, "lookup") Then
.Interior.ColorIndex = 36
End If
End With
Next
Exit Sub

NoFormulas:
MsgBox "No formulas found!"

End Sub

I need to implement cell protection to all cells with
lookup formula in a
worksheet. I know GOTO-Special can highlight all the
formula cells, but I
need some way more specific to pick and highlight only
the lookup formula.
