Custom List in Table Popup

Hello Experts,

I have a table popup that displays a chart. I would like to add a custom list to this popup to drive some changes in this chart, however, I’ve found that the popup does not recognise the settings key for the custom list when I try to use it.

For example, I tried a custom list with a settings key of $<<chartView>>. I then had a StrToSet combined with an IIF statement to drive the values in one of the dimensions of the chart in the popup based on the custom list (something we do successfully elsewhere), however, the MDX is not recognising the value in $<<chartView>>.

Do custom lists not work within table popups?

Thanks,
David
