From the fide laws of chess:
[b/]A pawn attacking a square crossed by an opponent's pawn which has advanced two squares in one move from its original square may capture this opponent's pawn as though the latter had been moved only one square. This capture may only be made on the move following this advance and is called an 'en passant' capture.[/b]
In order for your pawn on the a-file to capture the pawn that moved from b7 to b5, it would have had to be on a5, not a6. Being on a6, you would not have been able to capture his pawn had he moved only one square. Just remember, if someone moves their pawn two squares and that pawn lands directly to the left or right of a pawn of yours, then you will be able to capture en passant.

In game 290308 Black moved a pawn from B7 to B5. White has a pawn on A6. Why is it not possible for White to take the Black pawn using the En Passant rule? I am not being allowed to make that move.

Taking the b-pawn en-passant would mean that, while it is going from b7 over b6 to b5 in one move, you would have the chance - during the single next move - to take it at b6, the square it was 'passing'. But your pawn is one square too advanced to be able to take anything on b6.
I hope this is clear.
