Requiring Users to complete

Thanks. I played around with your suggestion and ended up with the following:I set the navigation buttons for each section(other than the first one) to be initially invisible. I created a variable for each section equal to 1. I created an action at the highest level to show each button if the variable is equal to 2. In each section, I created an action to modify the variable for that section to 2.When the on (release) { getURL('javascript:trivNextPage()') } takes the user to the next section, the variable is modifed and the button displays. It continues to display even if the user navigates backwards.Thanks for your help!!
