Hiding ticks and crosses in a Quiz

Have you made a quiz activity, and then found that the class use the ticks / crosses to remember the right and wrong answers the next time they attempt it? Wouldn't it be great if there were no ticks or crosses showing on the screen when an answer is chosen?

The code "_root.showScoreAlways=false;" hides the overall score (it normally appears in the top left of the screen)

The "_root.cross._width=0;" and "_root.cross._height=0;" codes make the cross appear on screen but with a width and height of 0 pixels - making it unnoticable. The same is true with the "_root.tick._width=0;" and "_root.tick._height=0;"

Try the Viking Quiz activity and see how these codes affect the score / tick and crosses.

Thanks to Dan and Max at 2Simple who thought about this one and sorted out a solution.
