Javascript: Can‘t get document.getelementbyid to work
<p>I found many questions concerning form elements that are null but I simply can‘t get this to work.</p>

<p>It works in every browser but when it‘s embedded in Wordpress it stops working in Firefox.
The Firefox-Console says I should use document.getelementbyid but in every way I try it, Firefox says the form is null or that "myform is not defined".</p>
