Hi stella24,
Welcome to Affinity Forums
There is an explanation of how to get the resources at the start of the book, on page 9.
Each chapter's files are provided on the beginning of each chapter or subchapter only. You can easily locate the link looking for the two overlapping files/documents icon on a blue background. In the chapter you mentioned it's on page 140 on top. The purple links referenced on the top of each page on that chapter are there just to reference the files that are being used/described on that specific page from the files you have downloaded for that chapter.
The files for the next chapter after the one you mentioned are on page 156 - again look for the overlapping files icon on a blue background -, and so on.
Stella - I found the best way (for me) to do this is spend the better part of a day, depend ending on your internet speed, downloading all the resource files from Https://affin.co/XXXX. I set up a new folder, in and external HDD, naming it for the workbook and then saved all the project files in that folder under subfolders with each projects name. Hope this will help you.
