I got to create a dynamic link like this:
<a href=" http://www.yqcomputer.com/
?Cat=333"> Select Category 333 </a><br>
In this case Category 333 comes from another page, and a request it thru
Response.Write("<a href=' http://www.yqcomputer.com/
Request.QueryString('Cat')" & "'>Select Category 333 </a><br>")
This for some reason doesn't work in ASP.net, can u guys help me out?
