Hi Excelers

here is the exercise:

Sheet1 is for inputs, Sheet2 to create a list and Sheet3 for output

Sheet one is to write raw input from B1:H1. Afterwards I need a button to copy the entire line and insert it on the first blank row in Sheet2 Range(B:H). If the line is already writen, it should paste it on the line bellow.
Sheet 2 has conditional formatting and filters and sorts but I will leave that to later.

I have to this over and over So I would like to save the copy paste step. What should I do?
MANY THANKS IN ADVANCE
