This time I'm writting down some tips for when you guys are playing around with the custom HTML tags or custom JavaScript variables not only for Google Tag Manager, but for any other TMS or website.
Most times due the projects deadlines or maybe just lazyness, the code we use (I include myself here), is not fail proof, and we need to think that we may broke some page functionality or even some page load. So using customHTML/custom JavaScript is a serious thing. Even a lot of companies are forbidden to use them in Google Tag Manager.
