storing activecell.row value for later use?

a=Activecell.Row

Activecell.Row
range("table1[location]").Select
selection.End(xlup).select
Offset(a, 0).select

With the above, once the selection changes on the second line of code the 'a' active row location number will be different as the current selected cell has changed

Is there a way to store the row number in the first 'ActiveCell.Row' line of code for reference in the 'Offset(a,0).Select

Many thanks
