Removed duplicate values from 2 lists to give only the unique values in list 3

Hi,

I only want columns G and H to pull through values that are not duplicated between Columns A and B and Columns D and E so the expected result would be pulling what I have typed into G and H.

I am expecting this to be simple enough, but can't seem to get it right.

Any help would be greatly appreciated.

Many thanks
Tom
