Formatting multiple choice data output

[ir_lnf]

I have a form with a multiple choice question where I can say which documents are missing from a file. The flow I'm setting up sends an email with that list of missing documents.

Currently, the list appears in the email like this: ["MLS","Listing Agreement","Purchase Agreement","DPOR","Summary of Rights"]

I'm trying to make it appear like this: 

MLS

Listing Agreement

Purchase Agreement

DPOR

Summary of Rights

I managed to get the formatting I wanted, but only with the full list of options. I can't seem to get that formatting with only the selected options from that form response. 

This is my current set up, which is not working at all and giving this error on the Join step: Unable to process template language expressions in action 'Join' inputs at line '1' and column '14442': 'Error setting value to 'From' on 'Microsoft.Azure.Workflows.Data.Operations.JoinActionInput'.'.

*Edit- This is my first time working in Power Automate so I may be missing something obvious.

Hi!

So you can convert your multiple choice response into an array by means of the following WDL expression...

split(replace(replace(replace(YOUR_FORMS_RESPONSE,'["',''),'"]',''),'","',','),',')

...as explained in this thread

Next, you can convert the array into a more readable format by following steps from this thread

Hope this helps

Is the first step still an Initialize Variable action?
