I have been getting the error ORA-00923: FROM keyword not found where expected and do not know why, please help

Answer

Identifiers need to be quoted with double quotes ("). Single quotes (') denote a character value (not a “name”).

Therefor you need to use:

SUM(part_gold) as "Number of Gold Medals"
