Hello,
I would like to present each image and question one time over the course of my survey. Right now, my script chooses images and questions randomly each time so that there is some repetition of certain stimuli and others are never presented.
How do I fix this problem?
My script is pasted below and I'd be so grateful for any help!

<page test>
In the next phase of the experiment, you will be presented with images and asked questions about your political beliefs. On each of the 25 trials, you will be shown an image for 3 seconds and then asked to indicate on a 1-7 scale, the extent to which you are 'for' or 'against' a given political issue. Please answer these questions as honestly as possible.

Please proceed to the next phase of the experiment.
