There are different stages with multiple possibilities in each. &nbsp;I can't see any east way to make this happen without using multi-dimensional matrix. The help file mentions the factor or row attribute to counters... is this implemented? I can't seem to get it to work. If not are there any alternatives that would work the same?<br/><br/>ThanksMon, 11 May 2015 01:26:20 GMTqman123https://forums.millisecond.com/Topic16250.aspxCan you give me a concrete example (using, say, 10 unique stimuli instead of the full 100) of exactly what you want to do? The description "There are different stages with multiple possibilities in each." is a bit too opaque for me to give any concrete advice. Thanks!<br/>Mon, 11 May 2015 01:26:20 GMTDave
