We do not comment on games in progress because some folks may take that as giving a player help during a game. It's kind of a gray area sometimes and I am probably getting close to crossing the line.
If you look closely at that link in my first post and compare it to your ongoing game you will surely see that there is a difference. Read the rule very closely, compare the squares involved, and you will answer your own question. It only applies to a very specific move made by a pawn on it's first move in a game.
Here's some more history on the "en passant" move. Surely this will help answer your question!
En passant (from French: in passing)
It is a special pawn capture which can occur immediately after a player moves a pawn two squares forward from its starting position, and an enemy pawn could have captured it had the same pawn moved only one square forward. The opponent captures the just-moved pawn as if taking it "as it passes" through the first square. The resulting position is the same as if the pawn had moved only one square forward and the enemy pawn had captured normally.
The en passant capture must be done on the very next turn, or the right to do so is lost. Such a move is the only occasion in chess in which a piece captures but does not move to the square of the captured piece. If an en passant capture is the only legal move available, it must be made. En passant capture is a common theme in chess compositions.
This rule was added in the 15th century when the rule giving pawns the option of initially moving two squares was introduced. It prevents a pawn from using the two-square advance to pass an adjacent enemy pawn without the risk of being captured.
