Hello Rick
Following your guidance, I also use the capitalisation method for variable names, but in addition I always compile after entering code to help catch errors.
I don't remember seeing youcompile during lessons.

That's because I never have errors. LOL. Ha ha. No... I'll compile when I'm DONE with a database, before I release a version to a client, or if I've got unexplained errors that I can't figure out. It is a good idea to compile often. Having "option explicit" pretty much makes sure that you declare all of your variables, and will catch misspellings of field names.

Seems like it would be essential to set up the relationship between Recipes and Products so that you cannot delete a product from the product table if the recipe still exists. That does beg the question of what happens if your recipe changes however.

Of course. I assume by the time you're at this level you understand the need for referential integrity - as you obviously do. Obi Wan has taught you well. I'm not going to take the time in every lesson to show you all of the stuff I've already taught you. Again. That's a lowly Expert-level concept. LOL. If the recipe changes, then what you require will also change. If someone changes it AFTER you make your shopping list, well, "dem's the breaks, kid."
