Hello

I have a subroutine that may or may not be presented with an array. If an
array has not been presented, then it should take the array from the current
worksheet:

Sub CreateTAPPIndex(Optional TAPPMatrix As Variant)
If IsEmpty(TAPPMatrix) Then
Rem This section understands when the matrix is a raw sheet versus a
presented array
Range("2:2").EntireRow.Delete
TAPPMatrix = Range("a1").CurrentRegion.Value
End If
End Sub

But if TAPPMatrix is undefined, it does NOT trigger a TRUE response from
IsEmpty. What am I doing wrong? Is there a better way?

Thank you

W
