En passant failure

Dear admins,

At my game nr. 6694739, after the move 23.b4 I want to reply 23. ...bxc2, however when I press the "submit" button the move is not validated.

Kindly please advice!

Excuse me for the typo and the inconvenience; obviously I had to write 23. ...axb2.

Yikes! Of course I am wrong, and this is not an en passant case!
Please feel free to shoot me😵

It was not a leg exactly, but this is exactly the proper time to pull my leg; enjoy it😵
