Question About Calculation Fields

Hi, I am making a calculation in Senaite, but I seem to be getting an error when I place this in the calculation: if [Ca] > 10: return [Ca] + [Mg] elif [Ca] < 10: return [Ca] - [Mg] I set Ca as 11 & Mg as 9 for the test calculation, but it says: Unspecified exception: invalid syntax There are currently no items in this folder. Can someone help me with this problem? Thank you very much!

For significant figures I will show my example as a new topic.
