Vitual List Column values disappearing

[agilbee]

I have a virtual column that selects a list of values from a related table. 

SELECT(Item Certifications[Certification Type],AND([Has Logo] = "TRUE",[Stock Item]=[_THISROW].[Stock Item]))

I want the values from this virtual column to be displayed in a table view.  When editing the formula I can see the data from the list populated in the preview panel.  This however is only temporaty and it disappears quite quickly. (Data is correct so Select is working).

In a detail view the values are also blank.  If I try to edit the record in a form view the values of the virtual column appear but are greyed out as I would expect.  Why are the values only showing up here and not in the other views?

I assume you attempting to display these in an Inline Table view?

Table Views require a list of rows - i.e. row keys - from the source the view is configured on.  The column [Certification Type] in your expression is probably NOT the row key?  Try switching it to the key column. 

Your virtual Column needs to be defined as LIST with REF as the Basetype and the source used in the VC needs to match that used in your Inline Table View.

I hope this helps!
