Rows 34-41, 83-90, and 132-139 are the row that are supposed to have the array of pictures. As you'll see also in those rows are audio stimuli, like "!clickvoogeme" that are audio clips asking the subject to click on one of the four pictures in the array.
I named the specific names of the image files as numbers so in the first group I have: 1,2,3,5,23,28,15,&17.
I am also attaching a slightly more cleaned up version of the spreadsheet.
Hope this helps!
