Creating the quiz chain.

1. Create all of your quiz files in hot potatoes.
2. Use the hot potatoes masher to create a unit or chain. (click here for a masher tutorial)
3. If you want to edit your index.htm do it now. I used Kompozer, free and relatively easy to use for the novice. 
4. Go back to your quiz files and set the 'next exercise URL' 
5. Set the 'next exercise URL' for your final quiz to index.htm (assuming you haven't changed the name from the masher default)
6. Make sure that all of the files are in 1 folder. Create a .zip file with that folder ready to upload it to moodle (you can do it by uploading single files but that will take much longer)
7. In moodle turn editing on and then go to add an activity - Hot Potatoes Quiz
8. Select choose or upload file
9. Upload your .zip file and click on 'unzip'
10. You will then need to select the file for the 1st quiz in your chain (not the .jms or the .htm) select choose. 
11. Make sure you change 'add quiz chain' to YES and 'show next quiz' to YES
12. All of the other options will depend on your course and your moodle
13. Click save and fingers crossed you will have a chain of quizzes!
