Hi there @genochkaaa, welcome to the Community!
If you’re looking to only continue the Zap for reviews that don’t contain any comments then the Does not exist filter rule would be the one to use.
The Does not exist filter rule would only allow the Zap to continue if there is no value present (meaning nothing exists) for the selected field. So if there’s a value in the Comments field then the filter would halt the Zap and no further actions would be carried out.
The (Text) Does not contain filter rule would check to see if the selected field contains a specific word or multiple words.
You can learn more about the different filter rules available here: Filter rule types
Hope that helps! If you try that Does not exist rule and it’s not working as expected let us know. Always happy to help further!
Wow! Thanks for you super prompt response! That makes a lot of sense! Thank you!
You’re most welcome @genochkaaa. Glad I could help!
