> the activities are 'mashed' unmashed ones show in the gradebook
Aha - I think this is the crucial bit of information. I had understood that no HotPots at all were in the gradebook, but I see now that HotPots containing actual quizzes (JCloze, JCross, JMatch, JMix, JQuiz) are in the gradebook, and HotPots containing masher files are not in the gradebook.
That is normal. The HotPot module does not know what to do with Masher files and ignores them, or rather it treats them as ordinary html files.
> can i get mashed files to show in the gradebook?
No. Basically a masher file is just a list of links to the quizzes. From the HotPot modules point of view, it is like a static html page and it is not possible to calculate a "score" or "grade" to give students just for looking at it.
Another way to think about it is that the list of HotPots on the Moodle course page replaces the list of links on the Masher page. In this respect, Moodle replaces the Masher.
