Hi Dirk,
It is correct that the 21 Hours displaying at the top of this screen is referencing the number of Hour records you have in this report. It is pulling that name form the name for individual records in your table, which in this instance is a bit confusing. Are you getting the sub totals in your reports on desktop by using Sorting and Grouping to get subtotals to display directly on the report? If so I can confirm that currently those totals based off of sorting and grouping do not display in the same way on your table reports on mobile. Instead to get a report with that information I would suggest building a summary report using the same grouping you are using in your table report and set up to summarize the fields you are using to track hours and then you can set that value to group by week or employee, etc depending on your criteria. It will currently pull them into the full screen version of the site but it will deliver a summary report that pulls those Totals.
If being able to see those Total and Subtotal values directly on your table reports in mobile would be helpful for your users I would suggest submitting that feedback to our User Voice request to help highlight its importance to your use of Quick Base. User Voice is a tool our Product Development team use to track feedback from our users on desired features or enhancements. The Quick Base User voice can most easily be accessed from the My Apps page in Quick Base by clicking on the orange Feedback tab that appears on the right of the page or at
http://quickbase.uservoice.com by signing in with your Quick Base credentials. If you do submit this feedback if you include a link to it in a response here in the community it can also help other builders with the same need to find it and add their vote as our mobile team continues to look at ways to enhance our mobile experience. I hope this information is helpful Dirk and thank you for your time today.
