I am managing a traffic database and have currently constructed a series of queries that list average vehicle speed and total volume in five-minute intervals over the course of several months. From each of these queries, I need to create a subquery that, for each time interval, will simply average all speed values and sum all volumes into one record. Fields are: Time, Avg Of Speed, Sum Of Volume.
I created the subquery like so:
When I attempt to switch to datasheet view though, Access locks up every time and I am forced to end the program through the task manager. The query I'm referencing [Speed Weekday (2 SB)] has only 4800 records thus far, so it isn't a ridiculous amount of data. Any advice as to what is going wrong? Thanks in advance for any help!

Code:
SELECT DISTINCTROW [Speed Weekday (2 SB)].Time, Avg([Speed Weekday (2 SB)].Speed) AS [Avg Of Speed], Sum([Speed Weekday (2 SB)].Volume) AS [Sum Of Volume]
FROM [Speed Weekday (2 SB)]
GROUP BY [Speed Weekday (2 SB)].Time;
