Data type mismatch when inserting into text field

Question

Hello all,
Using VB script and ASP.
I have a page that inserts into a field (casenum) in a table (clientsw) in a database. The field (casenum) in the table is data type TEXT :
I create a recordset and then an insert statement which the following is part of:
Code to insert the casenum into the field
rsClients("Casenum")=Right(Date(),2) & "E-100" & rsCasenumber("countervalue")
It inserts a number like 09E-1004500
I then have code that takes that string and passes it to the next page as a variable
Session("UserID")=rsClients("CASENUM")
response.redirect "done3.asp"
When it gets to the next page it is assigned as UserID
Dim svuserid
svuserid = "0"
if (Session("UserID") <> "") then svuserid = Session("UserID")
%>
My information inserts into the database exactly as I want it, but when it gets to the next page I get an error that is displayed that says the following:
Microsoft JET Database Engine error '80040e07'
Data type mismatch in criteria expression.
/done3.asp, line 16
My code on the second page is as follows:
<%@LANGUAGE="VBSCRIPT"%>
<!--#include file="Connections/connNewdatabase1.asp" -->
<%
Dim svuserid
svuserid = "0"
if (Session("UserID") <> "") then svuserid = Session("UserID")
%>
<%
set rsClients = Server.CreateObject("ADODB.Recordset")
rsClients.ActiveConnection = MM_connNewdatabase_STRING
rsClients.Source = "SELECT *  FROM CLIENTSW WHERE CASENUM=" + Replace(svuserid, "'", "''") + "  ORDER BY CASENUM"
rsClients.CursorType = 0
rsClients.CursorLocation = 2
rsClients.LockType = 3
rsClients.Open()
rsClients_numRows = 0
%>
Line 16 is the one that says rsClients.Open()
If I take the concatenation out of rsClients("Casenum")=Right(Date(),2) & "E-100" & rsCasenumber("countervalue") and have only rsClients("Casenum")=rsCasenumber("countervalue") and change the table field to number, I don't get the "datatype mismatch error"
What do I change to enable me to leave the above statement concatenated and insert into the table correctly and complete the stuff on the next page?

Sorry. In another thread I thought you mentioned using SQL Server

I didn't think that was the problem. I was just pointing out that it's a bad practice. If you use the '+' on two strings that can evaluate as numeric, it will actually add rather than concat them.
