Default month -1 (text box) (2003 SP2)

[Egg 'n' Bacon]

Silly little problem; I want to have a form text box open with last month showing as default. But I can't get it!

Tried this;
=Format(Now(),"mm")-1
and a couple of others, but nothing seems to make any difference.

To get the date 1 month before today:

=DateAdd("m",-1,Date())

If you only want to show the month, set the Format property of the text box to a custom format.
