Datalist control: dynamic link problem

[mister-Ed]

I am displaying subcategories in my datalist, and now I have a
bizarre thing happen when I add a new subcategory record in my sql
database, the new subcategory link does not click into the next page.
When clicking the link, nothing happens!:

code to link w/querystrings formatted:
<a href="prov-results1.aspx?county=<
%#Server.UrlEncode(Request.QueryString("county")) & "&subcat=" &
Server.UrlEncode((Eval("SubCategory").ToString())) & "&category=" &
Server.UrlEncode((Eval("Category").ToString())) & "&uregion=" &
Server.UrlEncode((Eval("uregion").ToString()))%>"> <%#
Eval("SubCategory")%></a>
url generated for working link:
http://www.lasvegasunions.info/prov-...+++&uregion=lv

a subcat link that i just added, but doesnt work; url generated for
non-working link:
http://www.lasvegasunions.info/prov-...tos&uregion=lv

when view sourcing in browser, this link works:
<a href="prov-results1.aspx?
county=Clark&subcat=Maintenance&category=Autos++++ +++++++++++++++++++++
+++++&uregion=lv">Maintenance</a>

view sourcing in browser, this link does not work:
<a href="prov-results1.aspx?
county=Clark&subcat=Auctions&category=Autos&uregio n=lv">Auctions</a>
....the link that works has spaces/+ signs in it, but I am stripping
spaces with Server.UrlEncode (?????)

TIA

...tried using the hyperlink/navigateurl method. This produced error
"server tag not well

formed"

<asp:HyperLink id="HyperLink1" runat="server"

NavigateUrl="prov-results1.aspx?county=<
%#Server.UrlEncode(Request.QueryString("county")) &

"&subcat=" & Server.UrlEncode((Eval("SubCategory").ToString())) &
"&category=" &

Server.UrlEncode((Eval("Category").ToString())) & "&uregion=" &

Server.UrlEncode((Eval("uregion").ToString()))%>"> <%#
Eval("SubCategory")%></asp:HyperLink>

.... I absolutely need these querystrings in this link.
