Can I add a progress bar that is attached to the check list?  
For example…  
I have a checklist with 150 rows. They get checked off in the app…  
I would like to have the progress bar at the top showing how many out of the total rows have been checked. And update in real time obviously.

Thanks in advance!

Create two Rollup columns. One to count all of the items and another one to count all of the items marked as true (checked). Then you can use those Rollup column values with the progress bar.

Thanks for the Reply! At the risk of sounding really dumb… What is a Rollup Column?
