hyperlink Border has no bottom border in ie7

[StickerAA]

Hi everyone, I want to put a border around a hyperlink but in IE7 the bottom border line is omitted and in Firefox it looks fine. Following is my html and css code. I have checked google to no avail. I have tried various position: relative/absolute combinations with no success.

Has anyone come across this bug before.
thanks

html code

<div id="page_content_container"> <h3> Products </h3>
 <div id="ATD_book_container">
  <div id="ATD_image_container"><img src="img.jpg" /><h4>Title</h4>
   <div id="ATD_text_container">
      <p> Some text ....</p
      <p> <a href="#" >Read More</a>  
         <a =href="#"> How to Order </a> </p>

CSS code

#page_content_container 
{ 
margin: 25px 0 0 0;
float:right;
width: 690px; 
height: 490px;

I checked your code and it is fine with both. Did you validate your HTML?
If not, validate your HTML first, and try again.

Hi Zero, the page validates fine. Here is the URL if you care to look at it. As I said it looks fine in Firefox but not in IE7.http://www.virtual-leap.com/client_developement_files/mohs_development_files/products.htm
