[AccessD] Help needed with DSum

I have the following query to try to get a running sum with a sum each
day. I am getting the same number each day. I probably have some simple
syntax error but am not seeing it. Her eis the SQL.

SELECT Injection.RecordDate, DSum("[Theoretical CO2] + [Theoretical
Water]","Injection","[RecordDate]=#" & [RecordDate] & "#") AS [Cum Inj]

FROM Injection

GROUP BY Injection.RecordDate;
