Contact Form 7 – Custom Validation

Hi there,

I read this article on the ct7-Site:
https://contactform7.com/2015/03/28/custom-validation/#more-13626

I inserted the code inside my Themeco X-Theme in the JS area, but it doesn’t work. Is this the right place to insert the code. Where do I have to insert the code?

Regards
Georg
