Selected Gallery - Extract Selected Items From Multi-Select Choice Column for Dataverse Data Source

[cmanning]

I have a working canvas app that previously used SP List as data source and now I am using Dataverse.  I have multiple errors to address since removing the SP list data sources and adding my new DV replacement tables.  In particular, I am struggling with converting a gallery's selected item data that is multi-select choice column type to its Dataverse equivalent.

Below is a screenshot of a screen from my app.  There is a gallery on the left column, HTML text in the middle column, and an HTML text in the right column.  I can't find an example of retrieving data from a selected gallery item (data is saved in column as "item1; item2; item3") and rendering it as HTML text in the Resource Types Requested from the screenshot below.

The Dataverse table, "DealIntakeApp" is shown below.

Here is the column name "ResourceTypesNeeded" that is populated when a user selects one or more items from a combo box on another screen. 

Here are the code examples I have tried as well the original code that worked for SP list data src.

// Works when using a SP list data src 
Concat( galleryLHAssignResources.Selected.'Resource-Types-Needed'.Value, Value, ", ") 

// Dataverse Approach 1 - Errors: "Concat has some invalid arguments" 
Concat( galleryLHAssignResources.Selected.cr4de_resourcetypesneeded.Value, Value, ", " ) 

// Dataverse Approach 2 - No errors but incomplete 
// How do I finish this to show selected values? 
Concat( galleryLHAssignResources.Selected.ResourceTypesNeeded.Value, ??

Anyone have any recommendations?

Option No. 1 : Is to use a Gallery Instead of the HTML Text

Option 2: Using the HTML Input will be using the Concat Function

Hope this helps!

@Mira_Ghaly - Thank you for your response!  I need to use the HTML text option since it will be better for performance.  Here is the code I tried based on your recommendation and there are errors in both the Concat & Text has some invalid arguments.  There is no reference to the specific multi-select choice column "ResourceTypesNeeded" (cr4de_resourcetypesneeded).  Any recommendations?  Thank you.  

// Concat & Text has some invalid arguments
Concat(galleryLHAssignResources.Selected.Choices, Text(ThisRecord.Value), "-")

You need to replace choices with ResourceTypesNeeded, it is just how it is named in my sample , sorry forget to mention you need to replace it.

@Mira_Ghaly - Thanks for the update.  I made this change  and it works! Thanks again!

Concat( galleryLHAssignResources.Selected.ResourceTypesNeeded, Text(ThisRecord.Value), ", ")
