I will change the code to one of the alternatives.  I guess the fix will
be included in the 2.8 release?  Also, did you create a bug report?  If
you did, what is the link?  I would like to include it in the commit
message when I make the change.

Doh!:)  Of course I meant to write:

    Dim counter as Int =
DirectCast(ScenarioContext.Current.Item("counter"), Integer)

Sorry I code in C# and I whipped that up pretty quick and I wasn't thinking.

Thanks, I will use this instead, since it is similar to what was causing
the bug.
