facebook app displaying username in a textbox
I am currently developing an application for my face book and for some reason i get the weird thing in and around my textbox you can see what i mean looking at
See where the textbox that has fb name in it then next to it is "/> how can i get rid of that and get the name of the user appear in the textbox?
This is my code for my username being dispalyed.
and the code of $F_user is
<input type="text" name="fuser" value="<?php echo $F_user;?>"><?php
So what is causing this problem?
$F_user='<fb:name uid="$fb_users" useyou="false" firstnameonly="true" linked="false"/>';
Can anyone help me with this?
