Unable to Queen Side Castle

I am unable to perform a Queen Side Castle and I should be able to, I have not been in check, all the spaces are clear, none of the spaces the King has to cross are under attack. Any ideas why I can't make this move?

Has the king been moved?

(Black to move)

I'm afraid it's illegal to castle Queenside on the Kingside.

Thank you for looking at this, I had forgotten that I moved my King eariler in the game. Sorry for the wasted question.

In other words, the king HAS moved.

P-

I think my reply was the best because I didn't comment on a game in progress. 😛

Snort! Great line. Rec'd.

Thank you for clearing up that rule for us. 😕

Note in the game diagram the only possible way to castle is K-side, yet the question was about Q-side castling. Heinzkat made a cute play on words that I thought was funny.
