TextArea Box Removes Text When Clicked On? How To Stop This?

[MiMa79]

Example URL: http://moviepostersdb.com/the-host/poster-1 On the above page on the right hand side under "Poster Embed Code" I have a text area that is support to have an image embed code.My problem is that whenever someone clicks in the box to copy/paste, all the text currently entered is removed. When they click away, it re-appears.From looking at the code below; does anyone see why this is happening?\[code\]<form action="#"><fieldset><textarea cols="37" rows="2"><a href="http://stackoverflow.com/questions/14595933/www.link.com" target="_blank"><img src="http://www.moviepostersdb.com/<?php echo $poster['image_large']; ?>" width="600" height="890" border="0" alt="<?php echo $movie['movie_name']; ?> <?php echo $poster['poster_name']; ?>" /> </a></textarea></fieldset></form>\[/code\]
