Hi I am trying to finish my form which is a room reservation form. The issue I am having is during the reservation I have a people and group field called attendees set for multiple identity input and I also have a locationattendee multi text field for my summary page. The summary page takes all the information entered about the reservation and shows it on one page for verification before the user submits. I have everything working great but when I try to use a rule to copy the attendees from the people and group field to show them on the summary page using the locationattendee field it doesn't work. I don't get any errors the field is just blank. I can set the default value but since I have multiple locations I need to use rules to set which attendees for which location in the summary page. If location + x then populate the field based on that locations attendees. Is there any way to achieve this?

Any chance I can see a copy of your form? I'd guess that you'll need to use a double eval to concat the display names of the person / group field, since it is probably repeating. https://johnliu.net/blog/2011/11/11/infopath-concat-sharepoint-list-with-the-eval-function-aka-v.html

I can't send a copy of the form but really strange this will not update using rules. I can add the group as a default value and it captures the information in the text box. I am looking at your link to see how this can work for me. I have tried many things but nothing seems to work.

What is your rule on? What is your rule action?
