Sum total on mobile differs from design

Hi Everyone,


I'm quite new to powerapps and the tech world in general, and I'm experiencing a rather confusing problem.

My data source is an excel sheet on Google Drive - with 144 rows of data. In design mode I have used the formula Sum(TYSales,Sales) which gives me a large total, about 1,000,000. When I view the app on my mobile the total reflecting is about 80,000 (I can see it is the sum of only a few specific rows).

I don't quite understand why my mobile app has a different value to what I see on my PC (in the design)? I also cannot determine why it has only selected specific rows to add up on the phone app.


Any help is appreciated. Thank you

Re: Sum total on mobile differs from design

Hi @ShaunO ,

I've made a similar test but not met the same problem like your description.

Could you show me more details about your app?

What's more, please try other data source, like one drive, to see whether the problem is the app, data source or device.

Here's a doc about system requirments, you could check it to see whether your device meets:
