The database I am working with has just 1 large table (which I know is ridiculous but 1 step at a time here). I need to produce a single query that displays 3 calculations. It seems easy enough but I am clearly missing something because I keep getting prompted with a "Enter Parameter" error. Currently, I have created 2 separate queries that calculate "Total Payment" and "Total Charge" now the final query is where I am having an issue. It displays the "Total Payment" and "Total Charge" correctly however I cannot get it to subtract the two and display in a third column named "Difference". Please let me know if any further info is required. I attached the SQL code. Thank you in advance!!!!
