style for images

Hi,

I created 36 rows of trials for an input file on direct Rt. and tried running it but it doesnt work. As you can see the stimuli is image and I have indicated under stimuli the approrpiate file location for the image, but the input file just doesnt run. Can anyone tell me what the problem is? I believe it has to do with style column? What code should i put for images? Here are two sample rows of the excel input sheet, all the other rows look similar only difference being trial number and the file name for the stimulus. Any help would be greatly appreciated. Here are the two rows:
block trial wgr style stim loc time 1 1 1 4 E:/3x3 target/3X3FSpT1.bmp 0,0,1 rt:38,30 1 2 1 4 E:/3x3 target/3X3FSpT2.bmp 0,0,1 rt:38,30

it didnt give the rows properly, but basically the style in here is style 4
