I am having trouble using conditions to control the location of a stimulus. I have an experiment that has

Experiment->conditions->Procedure->Timeline->Stim (see attachment)

The idea is to place the same grating at different points along the X axis. There are two variables: red (indicating whether the grating uses the red gun) and posit (where the x position is).

The experiment runs. However there are two problems:
1: Only 1 block runs (even when I ask for more than 1)
2: The stimulus always appears in the center - as though the posit variable is not being interpreted. The 'red' variable >is< being interpreted and the color of the stimulus changes across presentations.

Any thoughts?

Thanks

Alex

We could not find your attachment (send it to support@psykinematix.com if you cannot attached it here).

Have you check whether the experiment emits an error message when it stops (see the "Experiment log" drawer window under the "Designer" panel)?
