Please Help, I need to do a report on WORKLOGS

Hi There, 

i hope you can help me?
I have created a worklog group. When an engineer does work on a Request that is chargeable, he puts the hours in the worklog. I need to run a report for our customer with all the worklog/draw down that has been used so far. 
I have searched alot of forums and still can't generate the report, could you please help?

Thanks, Eimear
