I have a folder with a set of timesheets in it. If I create a method to sum a field called I_TimeTaken is this the correct syntax? --- <dtml-in "PARENTS[0].objectValues(['TimeSheet'])" size=1> <dtml-var total-I_TimeTaken> </dtml-in> --- To explain, this works but I'm interested to know if this is the right way. Specifically because I am now trying to write another routine which totals not just the current folder but the contents of any sub folders below and am running into problems (i.e. I can't do it). If the basic step is wrong I'd like to know before I use it in other places. Haven't managed to find anything in the archives but I think I may be suffering from docs overload. Many thanks for any help Ian Cottee (knee deep in Zope and way out of time)
