Why can I not make an en passant capture? Here is part of a Lichess game where I tried make to make an en passant capture-but it's impossible. The question is this-Why? I am new to chess. I searched for the chess of rules on Wikipedia, but there was nothing specific about this case.

[FEN ""]
1.e4 a6 2.d4 d6 3.Nf3 g6 4.Nc3 Bg7 5.Bd3 Nc6 6.Be3 Na5 7.O-O h6 8.Re1 Bf6 9.Qe2
b5 10.Rad1 b4 11.Nd5 Nc6 12.e5 Bxe5 13.dxe5 Bb7 14.e6 f5 *
From Wikipedia (is this what you read?)


  When a pawn advances two squares from its starting position and there is an opponent's pawn on an adjacent file next to its destination square, then the opponent's pawn can capture it en passant (in passing), and move to the square the pawn passed over. However, this can only be done on the very next move, otherwise the right to do so is forfeit. For example, if the black pawn has just advanced two squares from g7 (initial starting position) to g5, then the white pawn on f5 may take it via en passant on g6 (but only on white's next move).


The opponent moved 14...f7-f5. There is no White pawn on e5 or g5.
