Move Row to new sheet without overwriting

Hi all,

I found examples that get close to what I need, but can't quite adjust the code to finish it off (due to my lack of VBA knowledge). High level, what I'm trying to do is create a macro (button) that when clicked moves all rows that have "Complete" in column "E" to different worksheet named "Archive". The major hurdle i kept running into was if I ran the macro again, it would overwrite the existing data on the "Archive" worksheet. I want it to be, well, an archive and retain existing data, so it should paste in the first empty row. Also had issues with attempting to maintain two rows of headers/titles.

Attached is a sample workbook.

Let me know if additional info is needed and thanks for any help!

After adjusting some things I think this will work. Thank you!

My only issue is trying to figure the best way to calculate LastRow in your code. From what I can tell it currently counts the rows with content in Column A, so if I have nothing in column A for a particular row, it throws off the count.

Thanks Again!
