I have an ASP page that displays data from an access table. On the page i have a form button that calls another page that basically takes the data being diplayed and sends it to excel. This has been working for almost a year now suddenly, its not working. No cade has changed. The code to send the data to excel is attached below. Can anyone offer suggestions as to why this does not work anymore.
<%@ Language=VBScript %>

Dim arrMonths(11)
arrMonths(0) = "Jan"
arrMonths(1) = "Feb"
arrMonths(2) = "March"
arrMonths(3) = "April"
arrMonths(4) = "May"
arrMonths(5) = "June"
arrMonths(6) = "July"
arrMonths(7) = "Aug"
arrMonths(8) = "Sep"
arrMonths(9) = "Oct"
arrMonths(10) = "Nov"
arrMonths(11) = "Dec"

dim Rs
Dim strSQL
session("strSQL") = request("strSQL")

vMdbFile = Server.MapPath("\virtual\data\EnergySysVC\TiH.mdb")
	vConnStr = "Provider=Microsoft.Jet.OLEDB.4.0;Persist Security info=False;Data Source=" & vMdbFile	

		'Open Database Connection
		Set Conn = Server.CreateObject("ADODB.Connection")
		Conn.Open vConnStr

set Rs=server.createobject("ADODB.recordset")
Response.ContentType = "application/vnd.ms-excel"
Response.AddHeader "Content-Disposition", "attachment; filename=Enquiry_List.xls" 
strSQL = "SELECT * FROM tblTIHMetrics "
If Request.QueryString("Month") <> "" OR Request.QueryString("Year") <> "" OR Request.QueryString("Site") <> "" Then
     strSQL = strSQL & "WHERE"
End If
If Request.QueryString("Month") <> "" Then
      strSQL = strSQL & " month = '" & Request.QueryString("Month") & "'"
      If Request.QueryString("Year") <> "" OR Request.QueryString("Site") <> "" Then
            strSQL = strSQL & " and"
      End If
End If
If Request.QueryString("Year") <> "" Then
      strSQL = strSQL & " year = '" & Request.QueryString("Year") & "'"
      If Request.QueryString("Site") <> "" Then
            strSQL = strSQL & " and"
      End If
End If
If Request.QueryString("Site") <> "" Then
      strSQL = strSQL & " site = '" & Request.QueryString("Site") & "'"
End If
strSQL = strSQL & " ORDER BY 'site'"
'response.write strSQL
Rs.open strSQL,Conn,1,3

if Rs.eof <> true then
response.write "<table border=1>" & _

while not Rs.eof

in the past, up until recently when anyone clicked the "Export to excel" button on the page it sent the exact data on the page to an excel sheet called Enquiry_List.xls but now you click export to excel, it does nothing at all.

the button is on an ASP page and the button code looks like this.
<form method="post" action="export_to_excel.asp?Year=<%=Yr%>&Month=<%=Mth%>&Site=<%=Ste%>"><input type="Submit" value="Export to Excel"></form>
and the code from the "export_to_excel.asp code is what i posted attached to the question.

I would start by commenting out the:

Response.ContentType = "application/vnd.ms-excel"
Response.AddHeader "Content-Disposition", "attachment; filename=Enquiry_List.xls"

and then see if the server is throwing an error that you just couldn't see.
