picture.nontargetshape on Nback task

I downloaded the  Single Task Adaptive Nback task directly from the millisecond library. However, it does not seem to work. I must be doing something wrong. I get the following message, and no results are calculated:

picture.nontargetshape
unable to initialize <picture nontargetshape> item number 0. verify the item exists and is correctly defined.

How do I resolve this issue?

Correction: There is a minor mistake in the script's <list notargetvalue> element that can lead to the detailed error. 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>

tothe proper

<list notargetvalue>
/items = (1, 2, 3, 4, 5, 6, 7, 8)
/ not = (values.currenttarget)
/ selectionmode = random
/ replace = true

</list>
