Customise heading 1 style starting number in MS word 2007

Question

I am trying to get MS word to start a chapter number at 3.

I have set the Heading 1 style numbering format to start at 3 - this shows as 3 Heading 1 in the styles list. However, when I use the style for the document title it inserts a 1. I have tried right clicking and using set Number Value but it doesn't work.

My Heading 2 style already works (i.e. 3.1, 3.2, 3.3 is displayed when I use this style).

The reason I am doing this is to try to get word to number my figures as 3.1, 3.2 etc and apparently I need to do this first. See this question...

My figure captions show as 1.1,1.2,1.3 etc which seems to be related to the chapter number displayed.

Any suggestions?

EDIT

The approach set out here almost works but the caption numbers start from 0, not 3.

Finally managed to work it out:

I had previously set up a List Style which defined the starting number as 1. My headings were linked to this. To solve it I modified the existing list style to start at 3.
