In my Stroop experiment, I want to add a rating scale in after each block. The scale is used to assess affect rather than something concrete like an image that co-appears with the rating scale. I am trying to get the scale to appear so that the participant can use the mouse to select their affective position on a scale of 1-7: Completely Relaxed to Extremely Anxious. The parameters are at default and I’ve filled in scale description and labels. There is no correct answer clearly but I would like the responses to be recorded of course. The rating scale routine is located after the two trial blocks in this simple example study which is attached along with the error message I get.
