Attaching a field to the end of a hyperlink

[Ed H.]

I am using an up-to-date ACCESS 2003. I would like to attach a field from a
Table to the end of a hyperlink. I can't seem to use the HyperlinkSubAddress
to get the job done and I'm not a VB guy. The reason I need to do this is to
attach an Ebay Auction Item Number to the end of the Auction Item lookup
address. The example is:
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=3843421886 where
3843421886 is Ebay Auction Item Number "variable" that I need to append. The
Number is in a field in my Auction Item Table labeled: EbayAuctionItemNumber.
Can anyone help!

Thanks in advance.
