Product of Row Entries

P: 2
I need to find a way to get a product of a particular field across many rows.
Keeping it simple, my example table is as follows:

Month Montly Return (%)
Jan 20
Feb 10
Mar 25

Thus, my return for the quarter would be ((1.2)(1.1)(1.25))-1)=0.65=65%

In reality, the above is generated from another query in such a way that every month has a row entry, and every return is non-null, and everything is sorted by date.

The calculated value can go into another table, or another query, or can be stored as a variable in VB for all I care -- I just need the figure in some way shape or form.

Thanks
