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

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

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

Use <dtml-call "REQUEST.set('tree-colspan', value_that_you_want)"> -- Steve Alexander Software Engineer Cat-Box limited
