Should this code be on different lines? I'm using code from someone and it doesn't make sense to me. It's taking used range from one sheet and copying it, right? Doesn't there need to be a paste in the workbooks? It seems like workbooks should be on a different line. Also, what does the last part do with end (3) (2)?

.Sheets(i).UsedRange.Copy Workbooks("Master workbook.xlsx").Sheets("Master").Range("A" & Rows.Count).End(3)(2)
