Hello I want a single interger variable that can be accessed and updated from dtml files in various folders. I want to be able to do things like x=x+1 and ask what x is. what is the best way to do this in zope? Where might I read a tutorial on it? Please note I have classes and catalogs and sql methods working (to a certain degree!) but I really am having problems getting a simple solution to this problem. Presently I have set the variable as a property of a folder. I want to update it from a method inside a dtml file inside that folder, but have not been able to work out its address. I can read the variable, but I think that that is thanks to aquistion? Thanks for your time josh oN (sorry for cross postings on this topic, I won't post to zope dev anymore!)
