Lab and challenges out of sync. 3rd verification would not work although all steps followed correctly. Please take a look and update for future students.

On task 6, if you give the student the option of finding the solution by himself, "Check my progress" shouldn't check the query but either the result. My own query had an extra space after the comma in the WHERE SAFE_DIVIDE and the system were not accepting my answer. Jeez, that was frustrating :(
