InfoPath Dev

I created a form that receive data from a Sharepoint List which corresponding columns of multiple line types.
My problem is that even i cannot see these fields in my secondary data source.
How can i promote these fields?

What do you mean you cannot see them? As in--there is no data returned from SharePoint? Or that you don't have a table in the view?

I mean that in the Infopath Form in data connection wizard, i can see from the list all the columns except the column with type multiple lines

I'm not a SP expert, but it could be that InfoPath just doesn't support that data type, and that's why its not showing it.

Does someone with more SP experience want to jump in here to help out?
