Need help getting a label populating with the selected value of a combo box

This is a relatively easy thing to do typically. Simply drop the label and change the text property to something like ComboBox.Selected.RecordName. That usually works. But in my situation it fails.

Here is my issue. I am populating a form with data from a global variable. Now, the form gets populated as expected. The problem is that I have labels that look for the selected value and most work with the exception of the dependent combo boxes. These combo boxes are using code that looks like this for their DefaultSelectedItems.

{
 Value:
 If(
 varResetSubLedger,
 Blank(),
 Parent.Default
 )
 }

Now, there is a value in the combo box. Rolling over the Parent.Default in the code above shows me the expected value but the label doesn't show the selected value. The label is using this code.

CB_SubLedger.Selected.'Sub Ledger Name'

Rolling over 'Sub Ledger Name', in the previous code, says the selected value is blank. My other labels, not associated with child/dependent combo boxes, return a value. Seems like there is some issue with how I set the DefaultSelectdItems. I think. Anyone have an idea what is going on?

NOTE: For reference, I am checking varResetSubLedger because the parent is using this for the OnChange property

UpdateContext({varResetSubLedger: false});
UpdateContext({varResetSubLedger: true});

You are populating the combobox with a record based on Value: So that should be the name of the property that you reference in the Label. Try the following:

CB_SubLedger.Selected.Value

Sort(Filter('Cost Center Sub Ledgers', 'Cost Center Name' = CB_CostCenter.Selected.'Cost Center Name'), 'Sub Ledger Name' ,SortOrder.Ascending)

@futr_vision Is the Combobox set for Multiple Selections? If you click on Selected in the code what does Intellisense show you?

If you click on the dropdown next to the spot where it says selected is a Record you should see the key value pairs included in the record. One of them will be the text you want to be in the label. You need to use the Key that is next to that text.

That really doesn't help. The label is looking for data but what it finds is blank even thought there is a value in the combo box. The Parent.Default, when looking at this code in DefaultSelectedItems for the combo box, is text in this case

I guess the label is looking for a record which I think implies I need to update the code to return a record since it looks like it isn't. It's just returning code
