Boolean error when adding Cal events from Numbers

I’m getting a boolean error when I try and add multiple events to the calendar from Numbers. Really would appreciate help as it would make my life a lot easier.

Can you share a sample version of the Numbers file and details of the steps to reproduce?

Hey it seems to work fine now. I think because my computer is older it doesn’t run as smooth but all good I think. Would you still like me to attach the spreadsheet to take a look?

I’m fine if it is all working for you, but others may find it useful; I don’t personally use numbers - I spend a lot of time in Excel.
