Welcome to OpenStreetMap Richard, thanks for contributing to the map in Ghana.

In this edit I notice that you have changed a business/company to a school. What is the situation now? Does the business no longer exist or it has been converted to a school in the same premises? 

If you are unsure about the status of the business it is better to map the school as a new object and revert the business to its former status.

Best,
Sam
