I am using Dreamweaver MX and am trying to develop some sites for
school using DSN less connections using the function server.mappath. 
I have done this before, but now I would like to automate the process
using DW MX's capabilities.  My previous connection strings read:

Set conn = Server.CreateObject("ADODB.Connection")
set rs = server.CreateObject("ADODB.Recordset")
conn.ConnectionString = "DBQ=" &
Server.Mappath("database/investing.mdb") & ";Driver={Microsoft Access
Driver (*.mdb)};"
conn.open

This works fine on every page I've tried it on.  However, now I'm
trying to go into "Server
Behaviors"=>"+Recordset(RS)"=>"Define...(Connection"=>"New/Custom
Connection String"=>then putting the "conn.ConnectionString = "DBQ=" &
Server.Mappath("database/investing.mdb") & ";Driver={Microsoft Access
Driver (*.mdb)};" into the field where it asks for "Connection
String".  When I test it, I recieve the error "Format of the
initilization string does not conform to the OLE DB specifications."

What do I need to do to set up Dreamweaver MX with my DSN-less
server.mappath connection properly?
