Response.Write "</td>"
if sayac= 4 then
Response.Write "</tr>"
end if


rs.MoveNext
sayac = sayac + 1
Loop

rs.Close()
Set rs = nothing
%>

and this is my productDETAIL.asp codes
<%
id = Request.QueryString("urunID")
dosyayolu = Server.MapPath("urunler.mdb")
Set conn = Server.CreateObject("ADODB.Connection")
conn.Open "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & dosyayolu
Set rs = Server.CreateObject("Adodb.Recordset")
sql = "Select * FROM urunler WHERE urunID= '" & id & "' "
%>

default.asp page is working correctly but when i click a product link

http://www.cemoflower.com/asp/productDETAIL.asp?urunID=63

it's loading but the page is empty. No picture no error only blank.
How can i show the choosen products to productDETAIL.asp page ?

if the ID Column DataType is Integer, do not use single quote '', make it like this:
sql = "Select * FROM urunler WHERE urunID= " & id & " "
