Help me,


hello everybody.

I have a very simply flow with subtraction. Value A ("5" as example) minus Value B ("10" as example). The result ("-5" as example) should be entered in a SharePoint list. But I always get the following error:


What am I doing wrong?


Thank you for your help.

Hi @Danny2810 


Can you share a screenshot of the flow in edit mode and the expression you are using? Based on the error, for some reason, the value you are passing in the expression is null. You may also check in SharePoint if the columns that you are trying to perform this function on actually has data. 


Hope this Helps!
