Access database. Creation of forms for entering and displaying statistical data

Good day. A database is needed for entering and displaying statistical data

I will use the example of a product sales database by stores to demonstrate the structure of the database; I will enter the real names myself.

It is necessary to create forms for entering and displaying statistical data. I provide an example of the database. An example of the forms with explanations is in the Excel file (three forms on three sheets) 

Support for older versions of MS Office (from 2013) is preferred

If something is unclear, please ask. It seems nothing complicated.
