Sorting By Date

Hi,

I've just started playing with Access 2002 (Office XP) and I@m having a little bit of trouble.

I'm using the Query Wizard to summarise my database giving me average values for each month. When the query is first run it displays in the correct month order: April, May, June, July, August, September. But viewing the query again or when trying to graph the data in a Form, the sorting forces alphabetical order: April, August, July, June, May, September.

How can I get the query/form to return the results in true month order?

Here's the SQL info which the Wizard created:

SELECT DISTINCTROW Format$([Raw Data].[TimeStamp],'mmmm yyyy') AS [TimeStamp By Month], Avg([Raw Data].[Indoor Temperature]) AS [Avg Of Indoor Temperature], Min([Raw Data].[Indoor Temperature]) AS [Min Of Indoor Temperature], Max([Raw Data].[Indoor Temperature]) AS [Max Of Indoor Temperature]
FROM [Raw Data]
GROUP BY Format$([Raw Data].[TimeStamp],'mmmm yyyy'), Year([Raw Data].[TimeStamp])*12+DatePart('m',[Raw Data].[TimeStamp])-1;



Thanks in advance for your help.
