Thanks Michael, I think the ‘lag’ as I describe might be normal. With that said once the trials (2 total) are setup and I click run (the green button) the experiment doesn’t load. I don’t know any better way to describe it other than that. Also is this what you requested? (there wasn’t any custom code-to advanced for my knowledge of this).
