odata error with multiple responses in sharepoint list

[KatLane]

I have a SharePoint list that is used to record responses received via power app when a workplace incident occurs.

I have two columns that accept multiple options, as well as the ability to manually add text.  This is to specify any injuries sustained, and where they're injured on their body.

I'm using a compose action with html and dynamic content to create a document that is then saved as a pdf.  This document will then be signed by the employee and the manager, and saved in their employment file.

However I'm having difficulty getting the multiple answers to display correctly.

I want it to display like this:

With each answer on a separate line.

I can't use the same replace expression that I used for the witnesses section, as that is a string of free text, rather than an array of multiple selected answers.

Please help!  I've built flows before, so have a little understanding, but I'm self-taught through youtube and forums like this so please treat me like I have no clue.  This is also my first time working with html.

Thank you.

Hi @KatLane 

So I believe you are talking about a multi-choice column, So in this looks like below  in my example:

1. You need to construct an array representing your Choice Column as below:

2. Next Initialize a new string variable as a New Line Variable and in the Value Just Press Enter

3. Initialise a formatted string variable that you will pass to your document

4. Loop on the array of Multi-choice column from Step 1

Concatenation Expression Looks Like below for the compose action

concat(item(),variables('NewLine'),variables('StringFormatted'))

This is how it looks

Hope this helps!

Thank you so much for getting back to me so quickly!

I've hit an error at the first apply to each:

I think I missed something at step one, where I had used the same dynamic content as the output, when instead I should have used the value.  Making that change let the flow run error-free.

However, the formatting is a little out when I use this dynamic content 

I tried a replace expression, which gets close

replace(replace(replace(replace(variables('StringFormatted'),'[',''),']',''),'"',''),',','<br>')

But I can't get it to separate with a new line for each entry.

 Using the NewLine variable gives a blank response - no text at all.

 I'm sure there's something small I'm missing...

@Mira_Ghaly I figured it out!  I changed the new line variable to be a comma instead of a line break, then my replace expression worked and now I get each response on a new line!
