php form action breaks script

Hello list, I was just wondering if I could get some opinions on a snippet of code which breaks a php web page. First the working code which is basically an html form being echoed by php: if ($output_form) { echo '<br /><br /><form action="sendemail.php>" method="post" > <label for="subject">Subject of email:</label><br /> <input id="subject" name="subject" type="text" size="30" /><br /> <label for="elvismail">Body of email:</label><br /> <textarea id="elvismail" name="elvismail" rows="8" cols="40"></textarea><br /> <input type="submit" name="Submit" value="Submit" /> </form>'; } However if I change the form action to this, it breaks the page resulting in a white screen of death: if ($output_form) { echo '<br /><br /><form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post" > <label for="subject">Subject of email:</label><br /> <input id="subject" name="subject" type="text" size="30" /><br /> <label for="elvismail">Body of email:</label><br /> <textarea id="elvismail" name="elvismail" rows="8" cols="40"></textarea><br /> <input type="submit" name="Submit" value="Submit" /> </form>'; } Reverting the one line to this: echo '<br /><br /><form action="sendemail.php" method="post" > gets it working again. Now I don't know if it's an unbalanced quote mark or what's going on. But I'd appreciate any advice you may have. Best, tim -- GPG me!! gpg --keyserver pool.sks-keyservers.net --recv-keys F186197B
