The fix is to change the erroneous /selectionmode specification <list notargetvalue> /items = (1, 2, 3, 4, 5, 6, 7, 8) / not = (values.currenttarget) / selectionmode = replace </list> to the proper <list notargetvalue> /items = (1, 2, 3, 4, 5, 6, 7, 8) / not = (values.currenttarget) / selectionmode = random / replace = true </list>

It is only starting the first 2 trials and then stops giving this error message: Unable to initialize <picture nontargetshape> item number 0. Verify the item exists and is correctly defined. We did not do any changes to the script after downloading it. Therefore I assume that others might have encounterd similar problems and as I am completely unfamiliar with programming support would be highly appreciated. Thanks for any help.
