Changing range selected with variable

I have some code that uses offset to select a column of numbers

    Range(HomeCell).Activate
    
    ActiveCell.Offset(6 + Shift, 1).Range("A1:A15").Copy

However, I want to vary the range depending on a parameter passed to the routine.
i.e. Range("A1:A15") can vary - it may not always be A15.

Initially I naively tried

ActiveCell.Offset(6 + Shift, 1).Range("A1:A(Roze-6)").Copy

but of course that didn't work.
I tried various attempts at using Cells method, and R1C1 notation but no luck

The Cells method selects but it is always in reference to the start of the spreadsheet not the active cell.

Any suggestions?

Thanks
