Multi-select or Checkbox Data Between Two Zoho Creator Applications

Multi-select or Checkbox Data Between Two Zoho Creator Applications

Hello,
I have two Zoho Creator Applications which are sharing data. Both Applications have a 'Checkbox' field-type, 'Department'.

In Flow, I set Application B (recipient) field to 'Use a Custom Value' and my custom value is set to: #{applicationA.Department}   (see attached image)

However this will either result with an error or null value upon Flow execution (see attached image).

I am currently using the Free version of Zoho Flow and have not exceeded any usage limits.

Please provide guidance on sharing data between List-type variables between Zoho Creator Applications.
