I've read a lot of the forums, but am still confused on how to add a repeating section to my O365 Nintex Form. It is similar to an Invoice where the repeating section is Project ID/Name list and an amount field. Should my main list form have a lookup to the Project ID/Name list and then the values of that repeating section be saved in an Line Item List?
A couple of post I read were saying to use a multiple line text field to save the XML, that just confuses me more. I feel this shouldn't be so complicated.
Is there a How-To on how to create something like this?
