Query about the formula
Hi experts, I am working on the core designer certification.
I have one of the tasks to calculate the percapita. To convert from country “total” data to “per-capita” data divide by the country's population. I am using this formula
numval(" Oil production (Etemad & Luciana) (terawatt-hours)") / numval("population")
but after applying this formula I am getting an empty output column. Guide me to get through this .
thankyou

This corresponds to step 5 of the certificate's instructions. In this step there is also a hint that tells us how to solve this problem:
Hint 2: The Formula page in the reference documentation shows the proper syntax for using formulas to read column values when the column names include spaces.
