working navigation but toggle does not open - html

Question

After nearly a week I am still struggling with toggle on navigation.
This is my current CSS, what I need to do now, is simply get the toggle to open, it did open before so something minor is stopping it now but I cant work it out. I do not really know much about CSS as I keep forgetting it, but I do not know javascript or jquery
.nav {
background-color: #3333FF;
width: 100%;

#hamburger {

}
.menu ul {

font-size: 18px;
color: white;
list-style-type: none;
margin: 0;
padding: 0;

Here is an example for this. You can try this code. It is fully tested. I hope it will help you. You can change colors and backgrounds as per needed in this code.
nav ul ul {
display: none;
}
nav ul ul li {
float: none;
}
nav li {
float: left;
list-style-type: none;
}
nav li a {
text-decoration: none;
display: inline-block;
margin: 10px 20px 5px 0;
padding: 8px 10px;
}
nav li a:link, nav li a:visited {
color: #646565;
background: #e8e9eb;
}
nav li a:link:hover, nav li a:visited:hover {
color: black;
}
nav li:hover ul {
display: block;
position: absolute;
}
input.toggle,
label.toggle {
display: none;
}
label.toggle {
font-weight: 900;
font-size: 1.2em;
padding: 10px 20px;
}
#media (max-width: 960px) {
nav {
display: none;
}
input.toggle, .toggle span {
display: none;
}
input[type=checkbox]:checked ~ nav, label.toggle {
display: block;
cursor: pointer;
}
nav li {
float: none;
}
nav li:hover ul {
display: block;
position: relative;
}
nav li ul {
display: block;
}
nav li ul li {
margin-left: 20px;
}
nav li a {
display: block;
margin-left: 20px;
}
}
<div class="wrapper">
<label class="toggle" for="toggle">☰ <span>Menue</span></label>
<input class="toggle" id="toggle" type="checkbox">
<nav>
<ul>
<li class="current">Home</li>
<li>News</li>
<li>Contacts</li>
<li>Policies</li>
<li>Members</li>
<li>Volunteer</li>
<li>Links</li>
</ul>
</nav>
</div>

Just change your selector from:
#toggle:checked+.menu {
display: block;
}
to:
#toggle:checked+ ul {
display: block;
}
See snippets below:

font-size: 18px;
color: white;
list-style-type: none;
margin: 0;
padding: 0;
}
.menu ul li {
text-align: center;
display: inline-block;
padding: 10px;
width: 11.11%;
}
.menu ul li a {
color: #fff;
text-decoration: none;
}
.menu li:visited {
background: #0000EE;

}
.menu li:active,
