I need to assign tree-colspan to a page-wide global variable so I can use t=
his value further down the page.=20

i.e.
<dtml-tree>
Set "_['tree-colspan'] to a page-wide accessible variable.
</dtml-tree>
=2E..
Now access it down here.

<dtml-let> would work, but you can't have start a let in a tree tag and fin=
ish outside.  It would have been if <dtml-let> didn't have a closing tag to=
 limit variable scope.

Thanks.
