This is the Main Menu, or "Switchboard", which should open first whenever you open the database. 

MENU ITEMS:

1. "Add new kit" - your data entry screen.  (See screenshot for that.)
2. "Edit kit information" - opens your data entry screen in 'edit' mode.
3. The next three options are pre-set reports I have created for your use.  They will sort the data you have entered (all of your kits) by either the kit names, the manufacturers, or by category/scale.  (See screenshot for sample of one of those.)
