Hi Sven, First off, I would try doing this in something other than a DTML method; a Python Script or External Method are better choices for logic. Here's a simple example using a Python Script: ## Script (Python) "randItems" ##bind container=container ##bind context=context ##bind namespace= ##bind script=script ##bind subpath=traverse_subpath ##parameters= ##title= ## # We'll need to use Python's whrandom module import whrandom # Your list of choices. We want 3 of these chosen at random bozo=['a','b','c','d','e','f','g','h','i','j'] # A list to hold the random selections RandomSelections = [] # Pick 3 random selections for i in range(3): # Grab a copy of the random selection RandomItem = whrandom.choice(bozo) # Remove the object from our list of choices bozo.remove(RandomItem) # Add the item to our list of random selections RandomSelections.append(RandomItem) # Return the list of random selections return RandomSelections Hope that helps. Eric.

hello,
i am making a dtml script that will choose 3 different objects and display them and i'm kindda stuck.
i think the process would be :
1] make a list of objects (dtml-let ?) 2] choose a random item from the list (or maybe choose all three at one time ?) 3] remove this item from the list 4] same player shoots again...
right now i'm able to make the list, to use whrandom.choice(xx) to get a random value, but i can't remove items from the list and once in a while i do get the same item twice (which i don't want happening).
maybe i don't do it the right way ;-)
