Convert combo box selected items into a string

I'm trying to send the selected items in a combo box to a string for output. I know I can out individual selected items several different ways but I can't figure out how to convert all of them into one contiuous string.

I can show the first;

First(ComboBox1.SelectedItems).Title

Or the last;

Last(ComboBox1.SelectedItems).Title

And I can find the number of selected items;

CountA(ComboBox1.SelectedItems.Title)

But how do I get the first last and everything in between?

Please explane how this is used?

To strip off the trailing comma: not the most elegant solution but it does the job

 

Left(Concat(ComboBox1.SelectedItems, Value & ","),Len(Concat(ComboBox1.SelectedItems, Value & ","))-1)

@csegoviaIt works pretty well. I wouldn't call it inelegant, when you consider the sort of monstrosities that can come out of the expression builder in Flow.

For those of you using an external source for your combo box items, I'd like to amend csegovia's formula to:

 

 

Left(Concat(YourComboBox.SelectedItems,Result&", "),Len(Concat(YourComboBox.SelectedItems,Result&", "))-2)

 

 

 

Perfect, thank you!

@cweaver Could you please tell me how you would add Left and Len into this formula.  I have not been able to resolve it so I can remove the trailing comma.  Thank you.  

Concat(cmbxEventSponsoringChapter.SelectedItems,(Concatenate(Acronymn,", ")))

This is what I resolved this with. 
Left(Concat(cmbxEventSponsoringChapter.SelectedItems,(Concatenate(Acronymn,", "))),Len(Concat(cmbxEventSponsoringChapter.SelectedItems,(Concatenate(Acronymn,", "))))-2)

Here is some example code for combobox items. List of ID's separated with a comma: 

Concat(
    ComboBox_multiselect.SelectedItems.ProductKey,
    Concatenate(
        Text(ProductKey),
        ","
    )
)

 and to get rit of the last (unwanted) comma:

Left(
    Concat(
        ComboBox_multiselect.SelectedItems.ProductKey,
        Concatenate(
            Text(ProductKey),
            ","
        )
    ),
    Len(
        Concat(
            ComboBox_multiselect.SelectedItems.ProductKey,
            Concatenate(
                Text(ProductKey),
                ","
            )
        )
    ) - 1
)

This results in a list of the ID's of the selected combo items, for example in a label:

PowerAppsCombo01

Sorry already solved above

You just need to take he last 2 characters off the string:

Left( Concat(ComboBox.SelectedItems, Product & ", " ), Len( Concat(ComboBox.SelectedItems, Product & ", " ) ) - 2 )
