Hi! everyone!

I am finishing a code, but I am not so luck with that part.

What I am tring to do is: I have 3 differents workbooks, I have to find the
hours to deliver each product. On the wb1 I have at least 5000 kinds of
products (not all are on wb2), i have to find the products that are on wb2
and wb2 and see what is its clasification, once i did it, i have to see days
to deliver on wb3 that is in days and change it to hours and return this
value on wb1 at the columm "hours to delivery", the ones that are not on wb2
has to stay without the periods to deliver. I've tried a lot of times, but
always there's an error with the code, and I am tired of looking for it and
cant imagine what could be
