I want to find the active cell in a list in another worksheet... this gets
and error on the WhatToFind line... any ideas?

ActiveCell.Copy
Range("z1").Select
ActiveCell.PasteSpecial xlPasteValues
Range("a1").Select
Dim rngToSearch As Range
Dim wks As Worksheet
Dim rngFound As Range
Dim WhatToFind As Variant

Application.ScreenUpdating = False
Sheets("Contacts").Select
Set wks = Sheets("Assignments")
Set rngToSearch = Sheets("contacts").Columns(1)
Set WhatToFind = wks.Range("z1").Value

Set rngFound = rngToSearch.find(what:=WhatToFind, LookIn:=xlValues,
lookat:=xlWhole)

If rngFound Is Nothing Then
MsgBox "error"
Else
rngFound.Select
End If
Application.ScreenUpdating = True
Application.Calculation = xlCalculationAutomatic

End Sub
