Copy columns based on header (Without header)

Hi guys,

I want to copy some columns to another sheet based on the header. But without copying the Headers itself.
I've attached the file in which I want to do it.

So the columns from sheet1 (A2:M2) downwards, have to be copied to the sheet INPUT range (A6:M6)...
But on sheet1, the order of the columns can be different, or there can be less columns (based on a dropdown list).

Can this be done?

Thanks in advance!
