InfoPath Dev

So my dilema.....

I am creating a form and one of my fields is MY (model year) which is a choice field, 08,09,10,11,12 ( I also have all the information in a SP list) and the other fields are Start Date (defined), Last Production Date(defined),  Annual Quanity(defined), and serial number range(defined), . How can I auto populate all these fields in the infopath form when the MY is chosen?

Not sure how to link all these together.

Kindly,

Shannon 

Can someone point me in the right direction?

Please and Thank You!

 Add rules to your Model Year field in the main data source for your form. When the Model Year is populated, you can set the values of your other fields - when you use the field picker to select the field from your SharePoint list, you'll have to click the Filter Data button and add a filter that Model Year in the SharePoint list is equal to the Model Year in the main data source. Attach your form under the options tab if you'd like me to add a sample rule. :)
