Description of the problem: I have uploaded a builder experiment on pavlovia, which contains loops and randomization. In the local version, I inserted an excel to contaion the condition parameters. However, when I run the experiment online, there occurs an error saying “unknown resourses” and I don’t know why…Hope someone can help me! Please!
