En Passent

I'm not the best at chess but am I miss understanding how this rule works?

Is the game and the move is 27w, shouldn't the bishop have taken the pawn en passent? Or have I missunderstood this and thus lost teh game pretty much to my missunderstanding!

I haven't looked at the game, but the first thing that comes to mind - bishops can't capture en passant! Only pawns can.

Ahh such a simple mistake, you're right thanks for the help, I'll chalk that one up to experience.
