Inserting/Updating to ADO (.MDB file)

[Matthew Tedder]

Could someone potentiall help me..   I'm getting a message saying that this operation 
is not supported.  It appears to be on the ->AddNew(); method.  How can I insert and 
update data in Access databases in my question.  What syntax can be used?  I've 
already got reading solved.

$rs->AddNew();
$rs->Fields('User')->{Value} = "Bubba";
$rs->Update();
