This one is still not found and it is in the CSV file - I just don't
get it why !

Most of the SKU's are not doubled in the CSV, but what I will do is to
create new function to compare each SKU so after it founds the SKU in
the file it will return right away to the DB loop.

Yes it will change after I create the new func.as I assume.

I will keep you posted THANK YOU
