Yup that was it stupid copy and paste error. Thanks for catching it :)

And here's something that does not make sense about your code:
- The way I read it, you are essentially selecting a random index number between 1 and 20 from list.pickerhl.

/ ontrialbegin = [values.g1 = list.pickerhl.nextvalue;
    values.oh1 = list.ohl1.item(list.pickerhl.currentvalue);
    values.ol1 = list.ohl2.item(list.pickerhl.currenvalue);
    values.p1 = list.phl.item(list.pickerhl.currentvalue);

and then try to pull the items *corresponding to that index number* from list.oh1, list.ohl2 and list.phl. You then move on to pick the next random index number from list.pickerhl and so forth.

The *problem* is that some of your <list>s *don't actually have any items corresponding to certain index numbers*. And that's where things will (and should) fail to evaluate.

<list ohl1>
/ items = (3.85, 3.85, 3.85, 3.85, 3.85, 2, 2, 2, 2, 2)
</list>

only has 10 items. Suppose the index drawn is 13. What should the list return? It has no 13th item. So the evaluation will fail for any index > 10. The same is true for

<list ohl2>
/ items = (.10, .10, .10, .10, .10, 1.60, 1.60, 1.60, 1.60, 1.60)
</list>

which also contains only 10 items (i.e., indices 1-10 will work, anything > 10 will not).

With 20 items

<list phl>
/ items = (.1, .2, .3, .4, .5, .6, .7, .8, .9, 1, .1, .2, .3, .4, .5, .6, .7, .8, .9, 1)
</list>

list.phl, however, is fine.

That didnt seem to fix it either. I have attached the file as its a lot of code.

Since you only posted a fraction of the code / something that cannot be easily run and inspected, this is somewhat of a guess: The problem, I believe, is how you specified <list pickerhl>.

Instead specify

<list pickerhl>
/ selectionmode = random
/ poolsize = 20
/ selectionrate = always
</list>

and in your /ontrialbegin attribute replace all instances of 'nextvalue' with 'nextindex' as well as all instances of 'currentvalue' with 'currentindex'.
