InfoPath Dev

Hello everyone, I want to create a custom list for companies, products and prices. for example A companies x products 1$, A companies y products 2$, A companies z products 3$, B companies x1 products 1,5$, B companies y1 products 2,5$ etc. And this list will be update. And there will be a infopath form for create invoice and i want to create a dropdown list for companies. The person who select the company, products and price will automatically fill another colums. I create it successfully. But When i create a autofill connection it use ID. Unfortunatelly when new company add i have to create new rules in infopath :( Can i create this automatically? When the person add company, producs and prices, infopath receive new data and show it in new form. (xml not update itseld too) Best Regards.

Hi :) I fixed my problem. I use formula like this; if dropdown is equal my title, set field value like this; xdXDocument:GetDOM("Masraf Listesi Data")/dfs:myFields/dfs:dataFields/d:SharePointListItem_RW/d:cqys[../d:Title = xdXDocument:get-DOM()/my:myFields/my:field1] Its works :)
