[AccessD] DSUM Function - HELP

I am trying to use the DSUM function in the following query to get a
running total of the field1 field. All I get is the total of the field
column on each line of the DSUM. What am I doing wrong or is this the
wrong function?

 

SELECT Table1.Date1, Table1.Field1, DSum("Field1","Table1") AS [Running
Total]

FROM Table1

GROUP BY Table1.Date1, Table1.Field1

ORDER BY Table1.Date1;
