At about 1:40, I use a Hyperlink field for the customer's website. For new databases, I now recommend Short Text for website addresses as well as email addresses. Hyperlink fields store extra information along with the address, which can make editing or exporting it confusing. You can leave this practice table as shown and keep following the course. My Hyperlinks video explains the difference and shows how to open a web page from a text field. That button example uses a little programming, so it is optional for now.
