ASP Insert page forward to blank Details page

I have a site that has been functioning for at least 5 years without issue.
This week, out of the blue, the Insert Record function is not loading a populated Detail Page.
It is as if the ID is not being forwarded.
I feel like if I could just change this line:
WA_redirectURL = "gallerypics_Detail.asp"
.... and specify the ID that it would load, but I was struggling with syntax. Finally I tried " gallerypics_Detail.asp?pCID=4671 (where that is the actual pCID of a record and it threw a Resourse not found error. I suspect I am matching the wrong parameter for the Detail page as there are 3 set.
<%
Dim WADAgallerypics__ParamSessionpCID
WADAgallerypics__ParamSessionpCID = "-1"
If (Session("WADA_Insert_gallerypics") <> "") Then
WADAgallerypics__ParamSessionpCID = Session("WADA_Insert_gallerypics")
End If
%>
<%
Dim WADAgallerypics__ParampCID2
WADAgallerypics__ParampCID2 = "-1"
If (Request.QueryString("pCID") <> "") Then
WADAgallerypics__ParampCID2 = Request.QueryString("pCID")
End If
%>
<%
Dim WADAgallerypics__ParampCID
WADAgallerypics__ParampCID = "-1"
If (Request.QueryString("pCID") <> "") Then
WADAgallerypics__ParampCID = Request.QueryString("pCID")
End If
%>

Again, this has happened on every instance of Insert on this site. These pages have not changed in years.

I do have a valid Session value setting prior to the Insert page loading, which is still available on the failed Details page. Is there a way I can call that Session Value in my Redirect URL and successfully load the page?

I'm wondering if the issue is that you turned off cookies and session cookies in your browser. If the page hasn't changed it is unlikely that the problem is with the code on the page at all.

No, that is not it. As I mentioned, I am setting a Session Value which works fine. That session value is the same ID number that should be populated by WADAgallerypics__ParampCID and WADAgallerypics__ParampCID2.

I'd have to look at the pages to diagnose it. I'd suggest a premier support ticket so we can do screen sharing and debug this together to make sure it is fixed.

That would be great. Could that be arranged for Wednesday or Thursday at a scheduled time (within reason?). If so I can submit the ticket.

Thursday I'm available all day. I'm in PST, so it may have to be in your afternoon if you are not on the west coast.

I do not see how to make a Premium Support request, however I am available on Thursday even into the evening. Please advise.

Please post back with a US phone number or Skype contact information in the private area and I'll contact you to schedule a time.
