A workaround has been found, thanks to an earlier post from Karim (Karim\_Bernardet1) about the very same error. I believe it has something to do with the type of single quote being keyed in.

A link to that thread for reference - [[ODK2] Calculation - #5 by Satish\_Ravishankar](https://forum.odk-x.org/t/odk2-calculation/363/5)

It would be useful to understand how to type in the correct single quote using the keyboard.  
In the interest of figuring out a solution rather than workaround, I will leave this topic as unsolved.
