How to avoid the "apply to each" nesting in sharepoint list with multiple selections enabled in certain columns

[KIBANG]

I have created a meeting request form, and I have created a flow where I put the meeting details into an email to the meeting organizer, along with a link to modify the meeting. I am able to add in values of every column (Title, location, meeting type, etc.) with no issue. The problem I am encountering is when I try to add in the meeting needs and presentation needs values into the body of the email. These two columns are multiple selections enabled, and when I try to add them into the body of the email, an "apply to each" nesting occurs when I try adding meeting needs value, then it nests again (apply to each 2) when I try to add the presentation needs value under it. If the user selects two items from each column ( breakout rooms, polls) and (PowerPoint, Streaming), it generates four emails to the user, with each variation of selected items from needs. I only want one email with all the meeting details. If there is a better way to accomplish this, I am very open to trying that. Please help!!! Screenshots attached for reference. First without the meeting needs, and then after I try to add them.

You need to collect the Presenters or any other file with multiple items in a variable using concatenate and move the email step outside and use the generated variable or compose action instead.

Hi Mira,

thank you so much for the reply. I am a relative newbie, so I am not quite sure what you mean. If you could elaborate on these functions with more of a step by step, that would be greatly appreciated.

You need to do the below for any multi choice column

triggerOutputs()?['body/Presenter_x0028_s_x0029_']

Expression for Multivalued Field for my example which a field called presenters'

 In Bold is the field name in sharepoint

First Step is to Select Value from The Multi Choice Field into array then perform a join operation with whatever field you 

You can then use the output of the Join Step in your email sending step.

Hope this explains it a little bit more!

I have included the flow screenshots for reference. I am definitely missing something, just not sure what it is.

On this step you need to select Mapping Needs Value, i can't actually see if you are already selecting it or no

Mira,

That did the trick. Thank you so much for all your help!
