IndexZ syntax error in rhino 7

I am getting a Syntax Error when i try to run IndexZ. It is working fine on my friend’s rhino 7. Can anyone suggest a solution please? Its my first time using Rhino too.

Hi Saira -

I’d suggest to try to contact the author of that plug-in.
There appears to be an email address on the F4R page - Indexz | Food4Rhino
