Hello evertone,

I ran this code provided by our instructor,

and I did not really understand why there were two missing values for the last two columns,

and what did they mean?

Is there anyone who can help me with this?

Thank you much!

The instructor had a small oversight.  The INPUT statement creates DATE (not SaleDate).  So the calculation for MONTH should be:

month = month(date);
