Dear Team, Iam trying to solve Practice1 from Lesson 3 of Foundation course as directed in the Workflow.

trying to extract rows where clubmembers filed matches yes string and store them in clubMembers variable, thru command names.Select("[Club Member]=‘Yes’ ")

however getting this error

The error is ‘names’ is not declared. It may not be accessible due to its protection level.

Please change the scope of the names variable in the variables panel.
