Randomizing question

Hello,

I am having a problem with randomizing my trials. I am trying to order my trials so I have a random chance of getting a trial from any of my conditions. I have entered trail numbers into the bgr columns, but only half of my experiment seems to have been randomized. If you look at my csv file, you will see that the first part of the experiment is "moving" images, and the second half is non-moving. When I play my file, it randomizes between the moving stimuli first then after all moving trials are complete moves on to the non-moving. I would like the moving and non-moving to be intermixed. Is there anyway to do this with Direct RT 2008?
