How to create a command button to transfer CALCULATED data to another worksheet

I need help creating a template that I will use to import data that will be summarized and calculated for certain percentages.

What I need help on is creating a COMMAND BUTTON that when pressed will transfer the data in the next line on worksheet 1.

So this is the process.

- I copy and paste (import) the data to worksheet 3.
- Using defined names for ranges in worksheet 3, calculations such as total number of data (rows), percentage etc will be calculated in worksheet 2
- THE COMMAND BUTTON WILL BE ON WORKSHEET 2 that will transfer the result to the next row on worksheet one.

The point is, the data being pasted on worksheet 3 will constantly change every month but I want to keep a track of month to month change on worksheet 1.

I hope I explained myself well.

I've attached the test template

Thanks for the help
