i wanna use the 'http://www.dhtmlgoodies.com/index.html?whichScript=arrange-nodes-2'-script like in demo2
there are no problems if i run the demo. but if i copy the script to my project, the boxes don't get dragable. on debugging i found out that in function initdragableElements() the var dragableElementsParentBox 'has no properties' (firefox tells me). so the script stops in 4th line of this function.
i can't understand because it's a 1:1 copy of the demo-script. where is the problem???
