Create reports with related modules

Create reports with related modules

Hope someone can help here, or I need to contact support I just dont know what I'm doing wrong.

I start to create a report I select the main Module ie Contacts, I then select 2 related modules Potential business and say accounts.

I then have in the available columns all my fields from my related modules I then choose the ones I want,  move them into the selected columns and run the report however the report contains no information from the 2 related modules.

What am i missing ? anyone 

Many Thanks
