Sum of calculated field shows false result

[hpc1]

Dear community,

I made a calculated field in a SharePoint list. Then I created a gallery listing these calculated figures which look okay. However when I make a sum of these Numbers I get a totally wrong result. Screenshot is attached.

What happens here and how can I proceed to get the right result, which should be 3.55?

Thanks for help!

Don't use calculated fields in SharePoint.  Do the calculations in  PowerApps and save them to a Number type field in SharePoint.

@hpc1 ,

Try to use ( I hope i'm not mistaken that you are from Germany):

Sum(Gallery8.AllItems,Value(NotenWert,"de"))

Hope it helps !

Thanks for your reply. I'm from Switzerland. Oddly enough "de" doesn't work but "en" does.
