Reset multiple variables to default values

Thanks, Ashley! I am adding the course here as an attachment (formatted for Web Delivery). As an aside, should I try using numerous triggers in Storyline (no Javascript) to reset the variables instead of JavaScript?

Testers: Please begin the course by clicking on the "First Floor" caption. Mouse over and choose a section and remember your color. Click on that section and view the evacuation route. Then hit the "Proceed to Outdoor Meeting Location" button that pops up at the end of the route. There is a brief layer or two of info, and then you get to the layer that shows you the color-coded outdoor location signs. Remember WHERE your sign is. On the next slide, click the sign that matches the color whose route you just viewed. On the "correct" screen, click the "Main Menu" button and try a SECOND route of a different color. Note how, after viewing the route for THAT second department/color, clicking on the correct outdoor sign color does NOT yield a correct screen :-(

Thank you for any help!
