Display duplicate entries in excel

Dave,

it just returns the row# in column E randomly. it has display items with no. of duplicate entries with a under a column heading "No. of duplicates"
For Ex: Tag id: 18019728 appears 4 times in the data - 1 + 3 duplicate.
Result can be shown in a new sheet so that user won't be confused and raw data remains the same.

Sorry to bother you. Thanks for your time
