I actually figured out what I was trying to do. I wanted to create a data connection to a SharePoint list to prepopulate fields in my infopath form, using infopath feilds to filter the data from SharePoint. I got it to work, but my only issue is it will only work for the information in the first list item in my SharePoint list. My question now is how to tell the field to look through the entire list instead of just the first item?
Below is the formula that I assigned to the infopath field that pulls information from the SharePoint data connection "Secondary Data Source":
@ows_Manager[@ows_Store = field39]
The formula is asking the field to display a managers name from the SharePoint list when the Store equals the value of Field 39.
This formula will work with the first store in my list, but when pick the second store the field becomes blank. I am obvoisly still learning the basics of Infopath, so this answer probably seems easy to someone. I appreciate any help.
