Roll-up Summary in "Group By Summary"

Hi everybody,

I wanted to show a Roll-up Baseline Summary Bar in "Group By Summary"... I changed the fields in "from" & "to" in bar chart by "baseline start" & "baseline finish" respectively... & I put the Group By Summary in the "show..." field...., but it did not show what i wanted...

Is anybody there encountered same problem I have...

regards,
