Resetting Check Boxes

Learners need to find 5 values on a list based on criteria they learned about in previous chapters. The Grand Total s/b 6. They are started off with one selection made and the count set @ 1.

To encourage learners to make thoughtful selections (instead of just clicking all the options until the 5 are found), I added an Incorrect Count box. The page is currently set up with actions happening when users hit "Next". If the incorrect count is more than 3, I managed to get the counts to reset, but the check boxes do not reset. They remain selected.

Ideally this is what I would like to have happen:

Once the incorrect count reaches 4, I'd like to "show" a text box with this message: "More than 3 incorrect selections made. Click here (meaning the message box) to reset the page and try again."

I tried linking actions with conditions to the ICSWorongScoreKeeper text box but I can't get the message to appear nor to get the check boxes to reset. (This part is not currently on the page.)

I posted "Selecting Themes" zip file with the relevant page.

Thanks.
