Sorry about that. It's a hard game to understand without having manipulated the tiles onesself. I have to relearn the scoring everytime I do it. I called up the gal who has the game and asked her to read parts of the instructions. The part that I think is relevant is from "scoring."

"Two or more words can be formed." "They are each counted up separately, with the common tile stack being counted separately for each word."

These scores can be the whoppers.
