Why does this code work, but the second set of code doesnt?

This works:
Code:
<div align="center">
<div style="border:1px solid #999999; width:255px; margin-bottom:5px;background-color:#F2F4FA;">
<form action="http://pub48.bravenet.com/emailfwd/senddata.php" method="post" enctype="multipart/form-data" style="margin:0px;">
<div style="background-color:#DBE0F5; padding:3px; font:12px arial; color:black;"><b>Online Contact Form</b></div>
<div style="padding:10px; font: normal 12px Arial; text-align:left;color:black;">What is your name?<br />
<input type="text" name="name" size="34" style="width:230px;" /><br />
Where are you from?<br /><input type="text" name="where" size="34" style="width:230px;" /><br>
E-mail address?<br /><input type="text" name="replyemail" size="34" style="width:230px;" /></div>
<div align="center">
<input type="submit" name="submit" value=" Send ">
<input type="hidden" name="usernum" size="1"  style="border: 0px solid black; height: 0px; width: 0px;" value="4077994829" /><input type="hidden"  style="border: 0px solid black; height: 0px; width: 0px;" name="MAX_FILE_SIZE" value="2000000"><input type="hidden"  style="border: 0px solid black; height: 0px; width: 0px;" name="cpv" value="2" />
<input type="reset" name="reset" value=" Clear "></div>
</form>
<div align="center" style="margin: 5px;"><a title="Free Email Forms from Bravenet.com" href="http://www.bravenet.com"><img src="http://assets.bravenet.com/cp/bn-emailfwd.gif" alt="Free Email Forms from Bravenet.com" border="0"></a></div>
</div>
</div>
