I thought I understood what you were saying in your reply, but it doesn't appear to be working the way I expected it to . . .
I went into Display -> Custom Fields and I added two textarea fields, "Ingredients" and "Beauty Tips" in the "item" table.
After doing so, I went to edit one of my existing products . . . I expected there to see "Ingredients" and "Beauty Tips" input boxes on the page, but no such luck . . . I have "Front-end", "Back-end Form", "Back-end Listing" all enabled . . . what am I doing wrong?
