Bullet tag issues in Firefox

[Ac1234]

Hi there,

I have a bulleted list that i am using to display certain items ..But if there is a ul tag within an li tag..it doesn't indent it and shows it close together in the next line

* This is great
* And so is this
*:confused: this is so cool

Even if "this is cool" has to be subitem its not showing as a subitem

this is the html code

<ul >
<li>This is great </li>
<li>And so is this
<ul>
<li>this is so cool </li>
</ul>
</li>
</ul>

It shows perfectly in IE.

Any help is appreciated..

Thanks in advance
AC
