Conversion table help

Hello,

I am in the process of converting old FrameMaker 5.5.6 unstructured documents to FrameMaker 8 structured. I am having an issue with my conversion table, specifically with tables.
I am trying to wrap the head, body and footer in a tgroup element, then wrap that tgroup element in a table. I am able to get the first part to work but am unable to get the tgroup to wrap in a table.
Here is what my conversion table looks like for the items:

TE:(E:thead?, E:tbody, E:tfoot?) >> tgroup

TE:(E:tgroup)+ >> table

I have tried different options trying to get the tgroup to wrap but have not had any success yet. What would I need to change to get this to work?

Thanks,

Tyler
