Hello,

Did you give the repeating section a name and did you connect the repeating section to a multiline text variable?  You are working with the multiline variable assigned to the repeating section and not the fields in the repeating section, right?

Can you also send a screenshot of the data entered on the form?

Kind regards,

I did and use that name in the first Query XML in the XPath query field. 

Here is the input section. 

I found the issue, but not sure how to solve it. It's because the fields inside the Repeating Section are lookup fields. I need to query the list first, but unsure how to configure it. Any ideas?

I ran into this same issue on a couple of my forms. What I had to do is add a Calculated Value control to my repeating section that looked up the text value of the ID of the item picked from the Look-up list. Then your repeating section XML contains both the look-up ID in the Look-up control and the text value of the look-up control in the Calculated Value Control.  Here's an example of my Calculated Value control "Product" for my "ProductID" Look-up control:

And here's the XML of both the "ProductID" (look-up) and Product (calculated value) for a sample item:

Then in your Query XML action, you can just assign the Calculated Value instead of the Look-up to the variable.
