List.asp based on Session UserID

Don't know what I'm missing. I am using the below code to open up a List.asp based on a single table (no joins). This table includes a field named "Assign_to". I want the page to load with only records where the "Assign_to" field matches the logged in user. I don't get a specific error, just that it can't load the page. ALL HELP GREATLY APPRECITED!
Sub ListOnLoad()

'** Check if specific record exists ****

strSQLExists = "select * from ISSUES where Assign_to ='Session("UserID")'"

set rsExists = CreateObject("ADODB.Recordset")

rsExists.Open strSQLExists, dbConnection
if not rsExists.eof then

' if record exists do something
else

' if dont exist do something else
end if

rsExists.Close : set rsExists = Nothing
End Sub
