Puzzling Behavior

I need help getting the output of my list to display properly...

What I have is a query that shows the most frequent status messages broken down by each day...here is sample data:

MsgTime     MessageName  MessageCount
11/12       Error ABC      199
11/12       Error XYZ      8
11/11       Error EFG      115
11/11       Error XYZ      24
11/11       Error ABC      3
11/10       Error DEF      234
11/10       Error ABC      9

What I'm trying to do is take that data set and put it into an SRS report so that it looks something like this:

11/12  Error ABC   Error XYZ
            199         8
11/11  Error EFG   Error XYZ   Error ABC
            115         24           3
11/10  Error DEF   Error ABC
            234         9

So, I'm trying to put this into a LIST control so I can get the formatting right, but I must be misunderstanding how the grouping should work. 

I need to group it right such that each date gets it's own "row" but each error gets it's own column with the count underneath it. 

The number of errors associated with a date is variable so I need the column grouping to handle an unknown number of dynamic columns per row.  Plus, the order of the columns is different each day because the most frequent error seen today may not be the most common tomorrow. 

Whatever I'm doing isn't working right...any ideas on how to get the groupings right so this comes out the way I've laid it out?
