Hi Chip,
the jump would probably work if you copied and pasted in the full URL of the HotPot activity you want to jump to. You can get that URL if you go to the Moodle course page, locate the HotPot activity you want to jump to, right-click on the link to that HotPot activity, copy the url and then paste it into the Hot Potatoes quiz you want to jump from.
Another possibility is to forget about the "Next" buttons in the Hot Potatoes exercise, and instead use the "Next activity" setting in the "Exit page" part of the settings page for the HotPot activity in Moodle. (see screenshot)
The help text for the "Next activity" says the following:
This setting specifies a Moodle activity to be done after this HotPot activity is completed. The optional grade is the minimum grade for this HotPot activity that is required before the next activity is shown.
The teacher can select a specific activity, or a one of the following general purpose settings:
- Next activity in this course
- Next activity in this section
- Next HotPot activity in this course
- Next HotPot activity in this section
If other exit page options are disabled and the student has achieved the required grade on this HotPot activity, the next activity will be shown straight away. Otherwise, the student will be shown a link to the next activity, which they can click when they are ready.
One further way you could do this is to use the TaskChain module. If you want to chain your Hot Potatoes exercises together, you may find that the Moodle TaskChain activity module fits better with how you imagine a set of Hot Potatoes exercises being linked together to form a single task chain.
