The updates to the sql parameters that I was referring to are the ones listed in the screen shots that office originally posted. Inside of the recordset you will have SQL variables listed as the parameters. It is these variable names that should not contain an underscore. So the update should not mean that you change the db but rather the names of these SQL variables inside of the recordset server behavior.
As for the redirecting have you been able to confirm that the update and insert are occurring? If they are occurring correctly then it is probably just a code order issue or something like that. Please post back with this info and also a copy of the insert and update pages in a zip file. I can take a look to help determine why the redirect is not happening.
