Word will not set the Numbering Value that I choose

To sort this out, I followed the steps below -

1. Right click the number
2. Click 'Adjust List Indents...'
3. Click 'More >>' (bottom left)
4. Untick the 'Restart lst after:' option on the right
5. Set 'Apply changes to:' to 'This point forward' (top right)
6. Click 'OK'
7. Right click the number again
8. Select 'Numbering -> Set numbering value...'
9. Select 'Continue from previous list'
10. Tick the 'Advance value (skip numbers)' box
11. Set the numbers to 1.2.1

Long winded, but it seems that I was unable to do this wihtout following steps 1-6, I guess because Word assumes that you would never intentionally want to start a list at 1.2.1.
