Group: Forum Members Posts: 19, Visits: 69	Hi I'm really confused about how to use 'lists'. I've tried to create a Minimal Worked Example below. I thought the aim of the 'list' element was to create a general-purpose class for storing any type of item. However, I can't seem to refer to the wordList in the wordText element. Can anyone help with this? Thanks Nick <list wordList> / items = ("dog", "cat") / select = sequence </list> <list responseList> / items = ("Y", "N") / selectionmode = list.wordlist.currentindex </list> <text wordText> / items = list.wordList.item / select = sequence </text> <trial wordTrial> / stimulusframes = [1 = wordText] / response = list.responseList.item </trial> <block wordBlock> / trials = [1-2 = wordTrial] </block> <expt exptBlock> / blocks = [1 = wordBlock] </expt>

What you are looking for in your example is the <item> element, i.e. you'll want to do <text wordText> / items = worditems / select = sequence </text> <item worditems> / 1 = "yes" / 2 = "no" </item> Apart from that <text wordText> / items = list.wordList.item / select = sequence </text> is wrong and would not return anything anyway.
