Assigned Fundraiser not displaying in Power Automate

@Reuben Schmitz
You do not need to use another apply to each on the fundraisers.

After your Get a constituent action action, you get a dynamic content of Fundraiser(s) (with a description of “The set of system record IDs for the fundraisers….”). What you can do is, use the List constituents action and in the Constituent ID field use the join() expression to join the fundraiser's system id with a comma (,):

join(outputs('Get_a_constituent_action')?['body/fundraisers'], ',')

You will get something like this as a result of the join(): 1111,2222,3333

This will give you all the constituents in an array for all the assigned fundraisers. You can then use the Select action to select only the name of the constituents as an array

in your append to array variable, yo ucan use the join() expression again, to join the mulitple assigned fundraiser(s) by a delimiter (i.e. semi-colon or comma)

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

You will get something like this as a result of the join(): John Smith; Mary Jones; Tom Hanks
