Hello,

Is there someone who can help me with this problem : I want to create a self-test system for my pupils. I want to make a slide where I put many boxes with numbers on it and every number is linked to a slide with a question behind it. They chose a number (choosing one randomly), click on it and get the slide with the question. If the question is been solved, the pupils need to go back to the first slide with all those numbers (link). So far ... no problem. But ... and now I have a problem : Is there within powerpoint a possibility (a trick) that the number they clicked on the first time is disappeared (or changed by color or ... any other solutions) so the pupils know wich numbers they still have to do . This change has to be permanent during the time that they make the test.

Someone has a solution (if possible) for this ?

Thanks.
