Get single or multiple values from an array and join them

Hi!

I built a flow which is working well, but I'd like to give an approver more information in the approval mail. The information comes from a Sharepoint list with multiple-value fields eg. Hardware(Smartphone, Laptop, ...). So it is possible that there are multiple values in the array or just one.

I tried it with:

Initialize variable

(Apply to each)

Compose: Hardware Value

(/Apply to each)

Join: Output from Compose; join with ;

Set variable: Output from Join

This had worked once in a test flow but when I modified the flow "Output from Compose" was not available anymore within "Join".

Is there another was to do it?

Join would be perfect to delimit the values and if there is only one value no delimitation character is added.

Can you post a screenshot?

Also, have you considered using a HTML action?

You use a select to set your header values (left column) and your values on the right.

Then send the output to a HTML table action

Then put the HTML output into your email HTML

Nice idea, but I would really like to have the values in a variable to work with it at other places as well.

Below you can see my test flow. As I said, this worked well once to add the compose output to the join but it's not reproduceable. When I move the join into the loop, I get an error.
