Question : Access 2007, adding date fields in a form

I have a form with a start date field, an end date field and a term field which I would like to calculate thus:

360StartDateTB+360TermTB=360EndDateTB
Ex: 08/30/2010+60 months=08/30/2015

I've tried it as an event expression and I've tried it as a code, neither worked.
On Update Expression: [360StartDateTB] + [360TermTB]
On Update Code: Me.Ctl360StartDateTB + Me.Ctl360TermTB (+ sign disappears when I go to next line, not sure if that has to do with the fields having Ctl in them)
or
=DateAdd("m",60,"08-aug-2010") (really need it to draw from the 360StartDateTB date)

I would like to make it calculate automatically in the 360EndDateTB field

Put this in the Data Source of your 360EndDateTB field

= DateAdd("m",360TermTB,360StarDateTB)
