Button Gauges

I have added the "Next Page" and "Fuel Fill Up" Button Gauge icons to my dash.  When I press either one it takes back to the home page.  My OEM fuel gauge is erratic so I need the Bluefire app to do its stated fuel remaining calculation.  What am I failing to do?

I have a 2002 Monaco Signature utilizing the J1708 protocol.

Thank you

Make sure your gauges are locked. I had the same problem.

That did it!  Thank you very very much.
