If you need any further help, let me know.

Also, try adding hidden input fields. It should still send the value through querystring with the GET method.

You probably don't even need middlecategory. If you wish, you should do it this way:
SQL = "SELECT TC.topcategory, DISTINCT(MC.middlecategory) "&_
"FROM tbtopcategory TC, tbmiddlecategory MC,...

Okay, then this is the way I would do it if you don't mind me rewriting:
Response.Write("<table width='570' border='1'>")

Do While Not RS.EOF
Response.Write("<tr>")

For i = 1 To 3
If...

it should go like this:

ondblclick="OnDetailsChg('<%=svrgContact%>')"

sub onDetailsChg(id)
response.redirect ("../asp/PalContactDetail.asp?id=" & id)
end sub

well did it work?

If not, test what HTTP_USER_AGENT puts out and bind MSIE to that.

now is this going to be done on page or doing a post to the server? Doing it on page in classic ASP is called javascript. On the server just requires a post to the server and a return will post...

you're welcome, I hope it helps.

the reason why your last code isn't working like you thought is because you are calling the <% %> when the server runs the code. Therefore, you are essentially setting session("imagecap...) 5 times,...
