Data from one form to another

Hello, hope everyone is doing well!

In my spreadsheet, I have labeled Data areas A and B
I need the information in Data A to autopopulate to Data B
As you can see...
Data A starts by zone number and the product on a particular day.
Data B starts by product and then the zone number on that same day as seen in Data A.

I always enter the data into Data A and I need the information to autopopulate into Data B
I have attached a spreadsheet and have manually entered the data in Data B to show an example, but in the end, I would like for it to autopopulate.
The states have no effect on the function, but I had to include them.

I tried to do this myself using an Array, but came up empty

Any help would be great.
