Hi Gil,
I downloaded the e-book and I’m thoroughly enjoying it so far. I’ve had a quick skim through the contents and it looks very thorough. I’ve spotted what may be a slight mistake in Chapter 2. For the second exercise, Step 5 and Step 6 refer to splitting the column called ‘Product Code’, but the exercise file has a column called ‘Product Number’. Further instructions refer to the field as ‘Product Number’.
