Hey, I'm having trouble accessing variables in a 2-dimensional list. Here's the creation code: <dtml-call "REQUEST.set('col', [])"> <dtml-in "_.range(0, 24)"> <dtml-call "col.append([])"> <dtml-let hour="_['sequence-item']"> <dtml-in "_.range(0, hour_divisions)"> <dtml-call "col[hour].append(0)"> </dtml-in> </dtml-let> </dtml-in> This creates a list variable, col, which contains 24 lists, each of which have <hour_divisions> elements of value 0. I can easily access the value of an element using: <dtml-var "col[index1][index2]"> However, the difficulty comes when trying to change the value of one of these elements. I've tried a handful of techniques, mostly offshoots of this: <dtml-call "REQUEST.set('col[index1][index2]', 5)"> to no avail. Does anyone have a solution to this? Thanks much... --Tim
