Guys, I used to copy paste a data from one file to another but the code always say error in that specific area.

Selection.End(xlDown).Offset(1, 0).Select

Is that because I merge the column in E2:E4 di BUKU BESAR SQUARE CAGE 2022?, I already try to make the code to E2, but still didn't run.
There is a way to run the code without change my data format?

Thanks
