List not showing bullets

I am really not understanding why this is not working. following list code with id mymenu is not showing bullets? Help me please
html:
<div id="mymenu">
<p>This is sample menu</p>
<ul>
<li><a href="#">sample menu1</a></li>
<li><a href="#">sample menu2</a></li>
<li><a href="#">sample menu3</a></li>
<li><a href="#">sample menu4</a></li>
<li><a href="#">sample menu5</a></li>
<li><a href="#">sample menu6 </a></li>
<li><a href="#">sample menu7</a></li>
</ul>
</div>

css:
#mymenu ul
{
margin:0;
padding:0;
width: 20%;
border-style:solid;
border-width:1px;
border-color:#B0D030;
}

#mymenu ul li
{
padding: .2em 1em;
}

Update, they were showing but so much to the left that I could not see them
That i fixed with list-style-position:inside;
OR
put this code in your ul li
code:
ul li {margin-left: 1em; text-indent: -1em;}
