PHP Newbie here, but here's my problem:

I'm trying to add a prompt to my delete story hyperlink, so that I won't accidentaly delete a story.

The current echo looks like this:
echo '<a class="editstorylink" href="deletestory.php?id=' .$row['id'] .'">';
echo '' . delete . '</a>';


I would like to add the following function inside the hyperlink (currently getting errors when i try to add it):
onClick="javascript:return confirm('Are you sure?')

I can't get it to work, any ideas?
