Naming range in a macro

Hello,

I am tyring to name a range say a14:d14 (working_cap_formula) and then copy of past into range a15:d15 (working_cap_paste).

I have set up a macro to do the sopy and paste process but would like to name the range in the macro to ensure if rows are deleted or inserted above row 14 then the macro will still find the ranges to copy from (working_cap_formula) and paste to working_cap_paste).

thanks
