Description of the problem:
This is seen before, but i need some help, because I have xlxs files as data in the psychopy builder script.
When i try to run the pilot on pavlovia, this comes up.
"We could not find a record for experiment designer: undefined
Please check the name and try again. If the error persists, contact Pavlovia’s administrator. "
