ASP XML problem

hi guys

I am trying to generate an RSS feed by using ASP script that cycles through all new items within a DB. the script works in that it does pull out what I want but the following code doesn't generate the correct URL within the <link> tag that links to the item page.

my generated page has the correct link of: /productpage.asp?category=1010&productdetail=100055

but once i have uploaded the xml file and read the feed in a reader the link is changed to

/productpage.asp?category=1010=100055

it doens't read the second querystring, any ideas why?

<%response.write "<item>"
   response.write "<title>"& artist(x) & " - " & title(x) & " (" & label(x) & ") &#163" & formatnumber(price(x)) &"</title>"
   response.write "<link> http://www.firstrhythm.co.uk/productpage.asp?category="&cat_ID(x) & "productdetail=" & ID(x) & "</link>"
   response.write "<description>"& desc(x)& " - " & " (" & page(x) & ")" & "</description>"
   response.write "</item>"
NEXT%>

I'm no 'proper' coder, so apologies if this isn't correct, but should it be the following - looks to be missing an '&' sign;

There are several "reserved" characters in XML, including the ampersand (&) character. Try using the Server.HTMLencode() function to convert your URL that you want to include:
