Seemed enough of a hint to me... :) --
From: xytsrm on 11 Oct 2009 10:11 I ran a simple test of UBound(): Dim A(10) As String Dim B() As String Sub Main() ReDim B(15) MsgBox "UBound(A): " & UBound(A) & vbCrLf & "UBound(B): " & UBound(B) End Sub UBound(A) returned 10 and UBound(B) returned 15. If the lower bound default is 0, and as I have not affected the lower bound, then apparently UBound() returns the number of elements not the index. X.

UBound() by itself only does it if the lower > bound is 1.

No, it's still the upper bound and there are 16 elements in the array -- count 'em from 0 - thru 15 --> ??? Mess w/ Option Base and see what happens. Also, please don't top post--makes follow conversation hard... --
From: xytsrm on 11 Oct 2009 11:05 dpb, Are you trying to say that ReDim A(10) is actually creating 11 elements 0-15? X.

dpb your right! I didn't read the discription of ReDim correctly. I thought ReDim() was dimensioning an absolute number of elements - its actually dimensioning the subscript, so the actual number of elements is one more then the ReDim(). X.
