Report Creating Question

Hi,

I am hoping that someone here with more knowledge on report creating on here will be able to assist.

Whenever I create a report that includes some of the other modules i get an awful lot of duplicated entries such as contact names or email addresses. I pulled off a report yesterday of over 5000 contacts, some accounts that only have one contact and i will see each of these names and email addresses multiple times for the account.

Is there anyway to stop this as I'm having to get rid of the duplicates in excel which I view as an unnecessary step if there is away to stop getting this? And because of this problem, this list of 5000 was in actual fact only 843 unique contacts and not 2000 per page of the report.
