VBA copy last row data of one sheet col B of workbook to another workbook sheet col A

[megaheinz]

Dear all,
I would need a modification of the VBA code in attached file "Output" in order to copy paste the data of the source sheet/file ("Source") starting in column B into another workbook sheet, but starting the output in column A!
So far it copies the data also starting in column B of the output file/sheet , but it should start at column A.
I am not able to figure out what needs to be modified.
Thanks a lot for any support
Best regards
