Get Count of values used in Multi Lookup

[simkessy]

I have a multi lookup field in my sharepoint. 

I would like to get the disctinct count of each value used in that field. 

For example if I have 2 records:

 1. Janet, Steve, Corey

2. Janet, Mike, Corey

I need a collection with these values:

Name, Count

Janet, 2

Steve, 1

Corey, 2

Mike, 1

Is it possible for my PowerApp to generate this collection on load?

Hi @simkessy 

To create a collection for your requirement, use the expression:

Clear(CountCollection);ForAll(MultiLookupList,ForAll(Persons,If(!(DisplayName in CountCollection.Name),Collect(CountCollection,{Name: DisplayName,Count:1}),Patch(CountCollection,LookUp(CountCollection,Name = DisplayName),{Count:LookUp(CountCollection,Name = DisplayName).Count + 1}))))

You can add this expression on "OnVisible" property of your screen. Here, I have created a collection(CountCollection) with two columns(Name, and Count) to store the distinct values. MultiLookupList is the name of My SharePoint list with a column Persons(they have an attribute Display Name to get the person's name) that has the multiple selected persons. So we are applying two loops to iterate over each person selected in every record.  There is an if condition to check if current person already exist in the list. If it exists, it updates the count or else, creates a new record.

Hope this Helps!
