+x+xI build a list, like so: <list category1> / items = ("01", "02", "03", "04", "05", "06", "07", "08", "09", "10", "11", "12", "13", "14", "15", "16") / replace = false </list>
<list category2> / items = ("17", "18", "19", "20", "21", "22", "23", "24", "25", "26", "27", "28", "29", "30", "31", "32") / replace = false </list>
<list catalogue> </list>
<values listbuilder> / delaytype = -1 / ct = 0 / ct2 = 0 / tester = "..." </values>
<block listbuilder> / trials = [1=listbuilder] </block>
<trial listbuilder> / ontrialbegin = [ values.delaytype+=1; values.ct+=1; if(values.delaytype==4){ values.delaytype=0; list.catalogue.appenditem(concat(concat(values.delaytype,"F"),list.category1.nextvalue)); list.catalogue.appenditem(concat(concat(values.delaytype,"O"),list.category2.nextvalue)) }else{ list.catalogue.appenditem(concat(concat(values.delaytype,"F"),list.category1.currentvalue)); list.catalogue.appenditem(concat(concat(values.delaytype,"O"),list.category2.currentvalue)); } ] / timeout=0 / branch=[ if(values.ct < 16*4){ trial.listbuilder } ] </trial> However, any subsequent call to list.catalogue.nextvalue causes an error and does not provide the next value. It says: element: list.catalogue attribute: nextvalue message: Expression '2F10' is invalid. Expression contains an unknown element or property name. It seems like Inquisit is trying to parse the list item... but I merely want to assign the item as a string to a variable. What should I do? The problem is the mixing of different data types -- integers (values.delaytype) and string literals "O" and "F". Due to the order of operations in your nested concat() statements, the resulting value will attempt to be interpreted as a numerical value, which it actually isn't. The solution is to effectively cast the value to a string data type by enclosing it in quotes. I've separated it into steps below for clarity: <list category1> / items = ("01", "02", "03", "04", "05", "06", "07", "08", "09", "10", "11", "12", "13", "14", "15", "16") / replace = false </list> <list category2> / items = ("17", "18", "19", "20", "21", "22", "23", "24", "25", "26", "27", "28", "29", "30", "31", "32") / replace = false </list> <list catalogue> </list> <values listbuilder> / delaytype = -1 / ct = 0 / ct2 = 0 / item = "" / tester = "..." </values> <block listbuilder> / trials = [1=listbuilder; 2-129=mytrial] </block> <trial listbuilder> / ontrialbegin = [ values.delaytype+=1; values.ct+=1; if(values.delaytype==4){ values.delaytype=0; values.item = concat(concat(values.delaytype,"F"),list.category1.nextvalue); values.item = concat(concat("~"", values.item), "~""); list.catalogue.appenditem(values.item); values.item = concat(concat(values.delaytype,"O"),list.category2.nextvalue); values.item = concat(concat("~"", values.item), "~""); list.catalogue.appenditem(values.item); }else{ values.item = concat(concat(values.delaytype,"F"),list.category1.currentvalue); values.item = concat(concat("~"", values.item), "~""); list.catalogue.appenditem(values.item); values.item = concat(concat(values.delaytype,"O"),list.category2.currentvalue); values.item = concat(concat("~"", values.item), "~""); list.catalogue.appenditem(values.item); } ] / timeout=0 / branch=[ if(values.ct < 16*4){ trial.listbuilder } ] </trial> <trial mytrial> / ontrialbegin = [ values.item = ""; values.item = list.catalogue.nextvalue; ] / stimulusframes = [1=mytext] / validresponse = (57) </trial> <text mytext> / items = ("<%values.item%>") </text> That worked. Thanks!
