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
