Adding/Subtracting Tables together

[Kram222]

Using supply, purchasing, and usage sheets.

I want the Supply sheet to be the database
The Grocery (purchasing) sheet to add the food to the supply list
And the Usage sheet to subtract from the supply sheet

I realize that it may need a Macro or 2 but i have no clue how to go about that.
If it does need a macro then i have attached Shapes that can be used by the macro
I have added this thread to the Formal topic because i'm sure it will need formulas mostly

Any Ideas how to go about this? I have no clue
