Code in text block won't publish

I have a similar problem as this one, I think: https://kriesi.at/support/topic/java-script-added-to-code-block-wont-publish/

I have a form on this page: http://techsavvysolutionsgroup.com/submit-a-ticket/

Right now it works fine, and if I edit the page, the code is there, but I have to update the url. It is a form using this code:

<form>
email <input type="text" id="email">
password <input type="password" id="password">
<button type="button" onclick="login();">Login</button>
<script type="text/javascript">
function login() {
var companyId = 'tsg5'; // <-- INSERT YOUR COMPANY ID HERE
var email = escape(document.getElementById('email').value);
var password = escape(document.getElementById('password').value);
var url = 'https://na.myconnectwise.net/v2015_4/services/system_io/customerportal/portal.html?company=' + companyId + '&txtemail=' + email + '&txtpass=' + password;
window.location.assign(url);
}
</script>
</form>

the ‘var url’ needs to be updated. The example above has the new code.

When I paste that in, I cannot save it. Clicking the save button does nothing. If I remove the form code, it saves no problem.

I don’t think I can save this in another directory as requested in the first example as it is a form and must appear here.

Thanks for your help.
