That worked perfectly.

Just a couple of questions.

Since I know that 1007 is not a primary form (as there is only one primary 
form), I assume I could just do:

<xsl:value-of select="(
   ancestor::form/preceding-sibling::form[@primary = 'true'] |
   ancestor::form/following-sibling::form[@primary = 'true']
   )[1]/@name"/>

Does ancestor::form look only at the direct ancesters - which is why it 
didn't find the siblings of the ancestor?

In ancestor::form/preceding-sibling::form, does it say:

Look at the ancestor named form then look at all the siblings named form 
that came before it (and the reverse for following-sibling)?

What does the [1] do?  Is this in case it passes back more than one result?

If there is only one result, do I need the [1]?

Thanks,
