Append to String Troubles

Sarah Homan

I have a long list of flows to get up and running for 2025 and I thought I had started with an easy one…

I have looked through the community and found a couple of other references, but it's not quite making sense. I am happy to also bring this to the Power Automate User Group.

I'm trying to append to string multiple Custom Field Descriptions separated by a “,”.

I first did a Filter Array to isolate the Category I wanted.

Then looped through the results in hopes of appending to string so all entries were in one field.

Expression in Compose: item()?['codetableentry_value']

I'm thinking I'm not using the apply to each correctly.

As always, thank you.

there is no need for the apply to each for the gift custom fields.

• list custom fields
• filter array
• select
  • select the “value” (don't need to specifically use the codetableentry_value, but you can) and don't “map” a field.
• set varaible (not append)
  • join(body('select'), ‘,’)

make sure to click the “icon” circle in red to remove the “2 fields”. Only need ONE field, and then select “value”

join(body('Select'), ', ')

It worked perfectly; I'll save this for future flows. Thank you
