I want to compare e remove duplicates of copied values in VBA - excel

Question

I have a question about the macro that I am running. I want to copy / paste the values cross sheet, but the target sheet I want to compare the values and remove duplicates of intercalated columns.
So, the copy and paste is working well, but to comparing and removing duplicates is not working.
Is there something else that I should try in my Macro?
