Beanshell parse exception

Question

I'm working in the following rule we created to add it to a task and run daily to remove all groups from users in the "Tango" OU in AD but the Domain Users group.

The powershell command works perfect but when we try tu run this rule we get the parse error.

Would you please help me find out what is it failing?

Thank you!
