Change column by cell value in ActiveRow

Hello,

I attach my file. I want to know its possible when I´m at some row for example on row 4 and in column Z or column AB is one from AF2 to AV2 than I want to copy column selected in Z or AB to AD from Z and to AE from AB.

Then when I change row by down arrow to row 5 and value in Z5 and AB5 is different then in row 4 then copy whole column selected in row Z5 from AF:AV to AD and copy whole column selected in AB5 from AF:AV to AE.

I hope someone understand

Its mistake by copy columns so data validation can be removed.
