Create Form from Datatable Rows

I am trying to create a form based on each row from a data table. I am trying to just get one value from each row and display it in the form as a proof of concept but the form is not being created. The error I am receiving is:

Any thoughts? Thanks

Hi @jpreziuso ,

Could you let us know what is the activity that you are using ? What is actually needed to be performed ?

I am reading an excel file into a DT and then trying to display the PO NBR as a proof of concept

@jpreziuso ,

Could you also provide us with the Expression that is used in the Assign activity ?


This is some documentation from UiPath on the error but I am not sure how it applies to my situation
