[ic] Authorizenet Assistance.

While we're talking about authorizenet module quirks, has anyone been
successful in transmitting the order number via the x_Invoice_Num variable?
 By default it is set to send $actual{mv_order_number}, but that variable
seems to be empty when the transaction occurs (as it doesn't show up in the
authorizenet transaction).  When I manually set x_Invoice_Num to a static
value, it DOES show up in the authorizenet transaction.  Any idea what
$actual{mv_order_number} does not contain what it should?  

Thanks mucho,
Jud
