Hi Elzaimer,
Your problem is caused by using a "non-english" environment. This causes the output of a calculation
with a floating answer with a , (comma) in it. But if you reuse this figure in a calculation the comma is not accepted as a decimal sign but as a
string. So SommeDesEcartsALaMoyenne concatenates the answers.
A solution can be: if you use the LitDev extension by placing LDUtilities.CurrentCulture="en-US" as the first line.
Or you can do the calculation with integers by multiplying with 10000 and rounding. For the display multiply with 0.00001
