InfoPath Dev

Hi I saw somewhere that a webservice could be used in making a Data connection to the list for this purpose; but I can't find that article or how to do it. Is that what you did? And can you give some more detail if so? I don't have access to SP Designer either..just infopath designer... thank you vin

I am interested in the method for using the calculated column..can you explain?   I am told there is a way to get through webservices but I may never get that information from the system admin..;-)   thank you   vin
