mRender problem: unable to form link to folder contents

Allan, I'm having a problem using nRender and I'm not sure what I am missing since I have used this property before and it worked perfectly. I am obviously missing something critical. Here is a link to the page where the problem occurs

www.paulandkirk.com/Debolt/data/ClientPages/DataTables/DataTables-1.10.4/extensions/Editor-1.3.3/examples/inline-editing/ClientInventory_join.html

Here the Product names are highlighted but when you hover the url shows the .pdf file is undefined.

This same approach works well on the following link

www.paulandkirk.com/Debolt/data/ClientPages/DataTables/masterInventory.html

Here is the code on the problem page:

www.paulandkirk.com/Debolt/data/ClientPages/DataTables/DataTables-1.10.4/extensions/Editor-1.3.3/examples/inline-editing/ClientInventory_join.html

Here is the code on the page causing the problem:

www.paulandkirk.com/Debolt/data/ClientPages/DataTables/DataTables-1.10.4/extensions/Editor-1.3.3/examples/inline-editing/ClientInventory_join.html

Note

1. The 2nd return statement in mRender is commented out as it refers to the location on my laptop.

2. When the page loads choose page 6 to get past those entries that are "null". The null entries are the result of deletions in some of the other tables referred to in the join.
