Fix my numbered paragraphs in MS Word

Hi.

I have a word doc whose numbered paragraphs aren't working properly.

I'm trying (although with different subject matter!) to create paragraphs with a hierarchy like th is:
1. MEAT
1.1 BEEF
1.1.1 BEEFBURGERS
1.1.2 BEEF SAUSAGES
1.2 PORK
1.2.1 PORK PIES
1.2.2 PORK SAUSAGES

2. VEG
2.1 WINTER VEG
2.1.1 PARSNIPS
2.1.2 CARROTS
2.2 SUMMER VEG
2.2.2 TOMATOES

I've done it, but it's going wrong after 2.0.

I will send you a link to the document once we agree the job.

Hope you can help!

Charlie
