I am having troubles targeting the urls on omething

[admin]

I have a table with a roleover effect so the background changes colour. Because i want to use iframes on my new site i require the link to open in the _parent frame. I cannot work out how to do it so if anyone knows please help me!<br />
<br />
Here is the HTML:<br />
<br />
<table border="0" width="2%" cellspacing="0" cellpadding="0" height="811"><br />
<tr onMouseOver="this.bgColor='#E0E0E0'; style.cursor='hand'" onMouseOut="this.bgColor='#F0F0F0'" onClick="location.href='http://www.yahoo.com'"> <br />
<td class="dropdown" height="9"><b><span style="font-size: 7.5pt; mso-bidi-font-size: 10.0pt; font-family: Verdana"><font color="#989498">&nbsp;Yahoo</font></span></b></td><br />
</tr><br />
<br />
Thanks!<!--content-->
