ADO Connection Problems

I am having problems making things happen in a Microsoft Access Database that I am connecting to through an ADO Connection using PHP. I know a little bit about PHP and how to code, but this is the first time I have played around with the ADO Connection and Command objects. I am getting no error messages or anything, but when I browse the database, my changes are not being posted. Here is an example of what I am trying to do. Hopefully, I am just missing a step along the way. $dbFile = '\\\\SERVER\\FOLDER\\BackEnd.mdb'; $conn = new COM('ADODB.Connection'); $conn->Open("DRIVER=Microsoft Access Driver (*.mdb);DBQ=$dbFile"); $cmd = new COM('ADODB.Command'); $cmd->ActiveConnection = $conn; $cmd->CommandText = "UPDATE TABLE1 SET FIELD1 = '$parm1' WHERE FIELD2 = '$parm2';"; $cmd->Prepared = TRUE; $RSet = $cmd->Execute(); Any assistance anyone can offer would be greatly appreciated. Thank you. Joe
