Do you see the single quotes there? You're returning strings instead of numbers.

I changed what you suggested and I still cant get the tests to go through, look at the test results:

Test Results:
Fixed tests
Tests
should return 1 litre: '1' should equal 1
Test Passed
should return 6 litres: '6' should equal 6
Test Passed
should return 5 litres: '5' should equal 5
should return 893 litres: '893' should equal 893
Test Passed

inexplicable lol.

Your function is printing the result instead of returning it, and also, you don't need to add that string to it, only return the number.

Please put table name in description ty
