By looking back at a previous experiment I have created it seems to appear whenever you have a loop to determine the conditions file you are calling in.
I made it so that the conditions file was no longer variable according to the if statement (as a test run) so just the file name conditionsAB.xlsx. Then I get a new error.
Traceback (most recent call last):
