flying a VORDME approach in A319?

[Guest gwi]

I've recently started using PSS's A319 (FS9, XP Pro). It's absolutely first rate, once you get your head 'round the very different flying philosophy of the Airbus.Without a flightplan in the MCDU, I can do an ILS approach with no problem. But how do I set up a VORD approach? I've tried entering the VOR freq and inbound course on the RADIO NAV page, then using the APP or LOC button, but the A/P won't capture the radial. Help appreciated.George [EGKA]
