How to filter out false notification on a number change

Hi, I’m monitoring the number 13 on a webpage, I need to know when it changes to 14. Sometimes I get a false notification/error to say the number has changed to 0. It won’t ever go to 0, so either a glitch on the website or other. My question is, how can I get it to monitor so it only looks for the number 14, or doesn’t give an error to say it’s changed to 0. Thanks.
