referenced footnote in a table in table not displaying

I have referenced a footnote in a table that is in a table, the reference and the footnote are both in the second table. When I publish the pdf, the footnote appears but the refereced one does not. I think the context should be under xref. But what should my context look like

If I add a new one it tells me that tgroup is not a parent of xref and that tgroup is not a parent of tgroup.

Thanks for any insight
