This AJAX server code returns a correct CustID:

 
<%
CustID=Session.Contents("CustID")
RecNum=Request.QueryString("RecNum")
Qty=Request.QueryString("Qty")
'Set conn=Server.CreateObject("ADODB.Connection")
'conn.Provider="Microsoft.Jet.OLEDB.4.0"
'conn.Open ("c:/inetpub/wwwroot/HawksWeb/Data/WebData.mdb")
'Set Items = Server.CreateObject("ADODB.RecordSet")
'Items.ActiveConnection = conn
'Items.Open("Select ProdID From Cart where CustId='"&CustID&"'")
'Items.Move(RecNum,1)
'ProdID = Items.Fields("ProdID")
'Items.close
'Set Items=nothing
'Items.Execute "Update Cart Set Qty='"&Qty&"' Where ProdID='"&ProdID&"' and CustID='"&CustID&"'"
'conn.close
'Set conn = nothing
Response.Write(CustID)
%>

This code, however returns Qty:

 
<%
CustID=Session.Contents("CustID")
RecNum=Request.QueryString("RecNum")
Qty=Request.QueryString("Qty")
Set conn=Server.CreateObject("ADODB.Connection")
'conn.Provider="Microsoft.Jet.OLEDB.4.0"
'conn.Open ("c:/inetpub/wwwroot/HawksWeb/Data/WebData.mdb")
'Set Items = Server.CreateObject("ADODB.RecordSet")
'Items.ActiveConnection = conn
'Items.Open("Select ProdID From Cart where CustId='"&CustID&"'")
'Items.Move(RecNum,1)
'ProdID = Items.Fields("ProdID")
'Items.close
'Set Items=nothing
'Items.Execute "Update Cart Set Qty='"&Qty&"' Where ProdID='"&ProdID&"' and CustID='"&CustID&"'"
'conn.close
'Set conn = nothing
Response.Write(CustID)
%>

I hope this makes sense to someone!

That's not AJAX. A = Asynchronous, J = Javascript, A = And, X = XML. It looks like you're just writing numerical values. If you wrote out an XML document, you wouldn't need to make 2 calls.

Why are you creating a connection to the database, in order to write session values?

I hope to God you aren't planning to "turn on" (uncomment) that code! If you run updates against your database from query string parameters, you're begging to get hacked back to the stone age!

Yeah, Ok and all that jazz... Why does

Set conn=Server.CreateObject("ADODB.Connection")

change my response.write?
