Hi Karim,

Looks like I’ve come across the same error.  
(My post, for reference - [Expression in condition column not successfully evaluated - #3 by Satish\_Ravishankar](https://forum.odk-x.org/t/expression-in-condition-column-not-successfully-evaluated/382/3))

I am also using LibreOffice Calc (sheets).  
Could you please explain the solution to me? I am not sure what you mean by “bad simple quotes”.

Thank you for your time.
