I have a premade script that selects the items at random but I am trying to change that. Any help would be greatly appreciated.Fri, 14 Feb 2014 01:33:55 GMTCutshakhttps://forums.millisecond.com/Topic12329.aspxYour description doesn't really paint a clear picture of what exactly you want to do. However, for starters, I recommend you take a look at using &lt;list&gt; elements for stimulus selection, particularly utilizing the /itemprobabilities attribute. Details and examples can be found in the documentation for said attribute.<br/>Fri, 14 Feb 2014 01:33:55 GMTDave
