New statistic: closed tickets in last month or still opened

[aiol]

Hi,

I am trying to create a new statistic in which tickets which meet any of these restrictions are shown:

• - The ticket has been closed during the last month

• - The ticket remains opened

I have tried to create this statistic using the "wizard" in the UI but I have been unable to create it correctly. I think that the statistic I have created only shows tickets which meet both restrictions. Is there any way that tickets that only meet one of the restrictions are shown also in the report?

Thanks in advance,
