Can you help with Extension Gauge App Inventor?

You don't need an extension, there is a lovely Gauge project available in the gallery: https://gallery.appinventor.mit.edu/search/time Look for GaugeGenerator2 [Snap4]

This project I downloaded from the MIT App Community, and they said to use it to make a gauge the same as they did, but in their project the gauge heading is not in the middle when rotating.
