Ryan,

Would not work,

cause "mm" stands for minutes, not Months

if you have the need for the day first :

go to the filed expression

type : =format(fields!fieldname.value,"dd/MM/yyyy") , gives 19/11/2009

=format(fields!fieldname.value,"MM/dd/YYYY"), gives 11/19/2009

=format(fields!fieldname.value,"yyyy/dd/MM"), gives 2009/19/11

you can also change the / by - or : of whatever separator you want to use

Hopes this helps you a bit.

Wkr,

Eddy
