conditional visibility - minor issues

• "type" = "road" and "type" = "path" should have single quotes for 'road' and 'path' (double quotes are for columns only)
• I think some people refer to this as "conditional logic" or even "skip logic" - maybe worth adding such keywords to the page for better searchability?
