Not a problem. Send me an invite if you want & I'll answer any question you may have. <<grin>> If I know the answer. I'll try to help.

thanks I am still learning the game

From the rules in part, it says:
However, discarding is not performed if the player has used all his or her tiles with the intention of ending the round - the player is required to use all the tiles in the hand.

I've also found the information here very helpful along with other players comments to the nugget. You want a Kong? Sorry, you can't have one.

lay three tiles but is not allowing me to discard my last tile
