Hi Gary, sorry. Hopefully Alain will get to it today - it seems to be an issue in the JS spreadsheet loading but that’s beyond my skill set
When he gets a chance he’ll surely “fix” rather than “workaround”, if I know Alain at all! 
For what it’s worth, we are hoping to have more help to handle PsychoJS bugs soon - right now there are rather a lot of things on one guy’s plate!

Oh, my apologies, but to follow up on the issue experienced by @PsyTechMMU this one was, not a problem in the conditions file, but a problem in the way the select rows code was handled. There are various ways to interpret the strings that can be added there (“1:5” or “1,2,3,” or “[1,2,3]” etc) one of those was incorrectly concatenating the strings rather than providing a list of strings. That explains why very users had experienced the problem - not many people are using that option in online studies. That bug has been tracked down and fixed on the 2022.1.1 release
