Problem in broadcasting

Hi,

I am trying to schedule a report to be broadcasted on a daily basis. I am setting the options through query designer. I am able to create the variant and make the settings for the report to be scheduled for a daily broad casting. When I check the setting it says that the report is scheduled. But it is not automatically sending the report to the users unless I manually hit the button "Execute". Is there any thing that I am missing? I need the report to be sent to the users every day at a specific time. Any advise please
