How can I replace the front panel on my Hotpoint Oven?

Hello - I hope someone can help please. I need to replace the fascia/front panel on my Hotpoint Oven (EW85), because the numbers have all rubbed off. But I can't work out how to take the old panel off - I have tried taking all the visible screws out but it still won't budge. The black surround is stopping it but I can't figure out how this could be removed...if this makes any sense! With many thanks, Fiona xx
