Has anyone used Test Manager Excel Plug-In.I am looking for some help with this plug-In.

What I am trying to achieve using this Plug-In:
Trying to get the numbers from the test cases(passed or fail) per day.When I tried to use the reports from the Test Manager they give me the numbers which includes a particular test case which failed earlier and then passed(counts it as 2). I want to include the testcase count as 1 which is pass(don't want to include the fail count for the same test case).
Any help will be appreciated.If there is any other way to achieve this, it will be great.
