Standard Standalone? (y/n) If not then what?: Standard Standalone
What are you trying to achieve?: a simple loop with images from excel
What did you try to make it work?: made sure the settings were exact to a previous working loop
What specifically went wrong when you tried that?:
Include pasted full error message if possible. “That didn’t work” is not enough information.
I have another loop before this point in the experiment that is working fine with the exact same information (importing pictures from excel, with set duration, etc.). The one difference is that this one has two parameters.
It keeps crashing though and this is all I know.
