Hi Rob,
I started a new project, here below is what you see as an product properties before you do anything:
So compaired to what appears into your video this is missing the cost and sale price so you go to add those attribute in settings:
There you notice it's missing so you add it!!! wrong!
Because when you want to edit the price strait from the database you discover this:
but as long as you didn't enter a value in the database, your product page looks like this:
which doesn't show any prices columns
after I included my set of price attribute the properties frame looks like this:
the prices you see there are the ones that I created, not the one of the database.
The properties frame shown below is the one of a product that has a database input:
There you can see that the attribute only appears in the properties frame when there is an input of the value in the database. And this is product related. a product without value will not be shown.
I understand I made something wrong but I was seriously missguided by the fact that your presentation make extensive use of product that has the price attributes populated in the database.
Hope it helps
