Hello - I'm creating a job application and want to have available job titles from another list in the same site just displayed as text on the form.  Nothing fancy  I'm a bit of a novice.  I've set up the External Data connection and then also a variable to pull the collection of Titles from the appropriate list.  All I'm receiving is commas displaying on the form. 
I'm using the the following:
convertToString([External data].[Job Title 4].[Records].[Title]) 
What is returned is: 
Job Title 4
,,,,
There are indeed 5 active job postings from a list of 150 or so, so the number of commas are correct, I just can't get the text of the Titles to display.  What am I missing?  Thank you for any help!
