To check if there is an error, we need to know what steps you took before all went wrong in your opinion.
Send an email to email@example.com with the subject "Error in calculation" and attach:
- The description of the sequence of your actions, so we can get the same result as you
- The description of the calculation discrepancies
- Screenshots that show the error
Use the function “Share this result on the results screen” if possible, so we can see the exact hand or situation where the problem occurred.
