## superscript with pointer

Hello,

I'm having a problem with this code:

I'm having problem with the following code:
CSS:
Code:
```.Sup {
color: #FF0000;
font-family: Arial;
font-weight: bold;
text-align: left;
}

HTML code:
<sup><span class="Sup"><a href="#ch04-10">10</a></sup></span>```
( flagged in yellow by Dreamweaver 8)

This would be for a text like : xxxxxxxxxxxxxx bbbb g ggg10 (where 10 is a supercript) and when cliked should point to a footnote in the same page.

That would be Chapter 4 Footnote #10

Question why this is not working?

Any ideas?

Thank you for any help.
