I might take a different approach by looking in the 60 item list (col K) for
each hit in the lookin list (col C). Something like this.

Sub findeachinlist()
On Error Resume Next
slr = Cells(Rows.Count, "k").End(xlUp).Row
On Error Resume Next
For Each c In Range("k3:k" & slr)
With Range("c1:c15")
Set c = .Find(c, lookat:=xlWhole, LookIn:=xlValues)
If Not c Is Nothing Then
firstAddress = c.Address
Do
MsgBox c & " found at " & c.Row
Set c = .FindNext(c)
Loop While Not c Is Nothing And c.Address < firstAddress
End If
End With
Next c

End Sub

Can't get this macro to work. Has something to do with the way I'm
listing
the values but I don't know how to do this properly. Also, I need to be
able
to list over 60 values (not just the 3 shown below), i just truncated for
this post. Please help!!!

Sub CheckNNumbers()
Dim RowNdx As Long
Dim LastRow As Long
StartRow = 2
LastRow = ActiveSheet.UsedRange.Rows.Count
For RowNdx = LastRow To 1 Step -1
If Cells(RowNdx, "R").Value = "N117CH" Or "N917SH" Or "N911WK" Then
MsgBox "Invalid Aircraft No."
End If
Next RowNdx
End Sub

Again, I just need to know how to "list" multiple values. I've tried
using
commas in place of the "Or" statements but nothing works! Please help!!!
