Nested Region Error in Explorer 7 but not Firefox

Question

Can any of you tell me why the following code generates an
error message when I attempt to view it in Explorer 7, while it
processes correctly in Firefox? It claims that it "Found a nested
spry:detailregion in the following markup." and points to the
<p>...</p> code shown below, along with it's
accompanying div statements.
<div id="ballet" class="SpryHiddenRegion"
spry:region="Olmannen" >
<p spry:repeat="Olmannen">{activity} {preposition}
<em onmouseover="Olmannen.setCurrentRow('{ds_RowID}');"
id="trigger"> {name}</em> {conjunction} <em
onmouseover="Olmannen.setCurrentRow('{ds_RowID}');"
id="trigger">{support}</p>
</div>

Answer 1

Hmm, Came back to the issue fresh today. Rearranged other
code a bit on the page and voilà, no more IE error. They both
work correctly now. It would be nice to know which change actually
made the difference I know. I may go back to play with it more
later, but for right now, I'm just going with a "divine providence"
and be really happy that it works. :)
