Can any one suggest to this dumbo how I can take two work sheets of
similar
sales data both of which are similar but some fields missing from both
respectfully and create a new work sheet that will report on the
difference
between them. I have ony been able to add them together with any success
using pivot tables which is quite frustrating
Thank you for any help
