Marker variable trigger

Your newer version must not be backwards compatible with mine, so I couldn't open your file.

However, essentially you would not need any variables, and ideally you would need only one variable, to better handle revisits to the screen/slide.

I put together a simple prototype.

• Create a T/F variable set to "false" 

• Add slide trigger to disable Next button if variable is "false"

• Add variable trigger to enable Next if that variable changes to "true"

• Add object trigger to set variable to "true" if all marker states are "visited"
