nested repeat region

[shank]

I'm trying to use code I found on:
http://www.dmxzone.com/ShowDetail.asp?NewsId=394&offset=5

I've used it before without issue, but this time it's not working. The
nested records are not being filtered. They are all displayed on the very
first request. <%=FilterParam%> shows that the correct KeyNumber is
requested, but still all records are displayed.
Can anyone see what I'm missing?
thanks!

Repeat1__numRows=Repeat1__numRows-1
rsItemKey.MoveNext()

never mind - found it
rsItemKeyProducts.Filter = "KeyNumber = '" & FilterParam & "'"
Code originally designed for numeric key fields
Mine are alpha-numeric
