I have an issue with my test stimulus Start time which is a variable (because it is different for different stimulus in my conditions file). I inserted the name of the variable:
If $Time22 is not defined, the variable or the condition file itself doesnt seem to be loaded correctly. (Format error could be more like ($Time22 is not a number)
Maybe you can share a screenshot of the loop where the condition file is loaded. If the file is loaded correctly, the loop Dialog would show the all available variables.
Screenshot of the builder routines and loops would be good to solve the Problem. Sometimes there is an easy solution that you try to use $Time22 before our outside the loop.
The aim is to show both text stimuli after 5 seconds (5 sec start time) during the the first loop. After that, they should show up immediately (0 sec):
