I am trying to run a subliminal test and although I've managed to get the exposure time down sufficiently I'm not happy with the flashing on the screen so I would like to set the subliminal part of the trial as purple on a black background so the flashing is less obvious. However when I try to insert a new style column before the second set of stim/loc/time in my trial the experiment won't run telling me I am missing a loc value in line 3. This is clearly not true as it runs fine when I remove the new style column. Is it not possible to have 2 different styles within the same trial?
