I created a new input file for a new study I am running, but when I try to run the file, an error message appears saying "Row 4 requests style file 0, which does not exist in the style file (.drt) for this session." The thing is, the number in the style column in row 4 is 1 (as it is for all trials in this input file) so I am not sure what is going on here. Any help would be appreciated!
