Answer 1

You've probably some JS errors, and need to add single quotes around your values :

$buttonMessage = '

 <a class="drupalchat-profile-un drupalchat_cng" 
 href="javascript:void(0)"    
 onclick="javascript:chatWith(\''.$pUsername.'\',\''.$profile_uid.'\',\''.$UserAvatar.'\',\''.$onof.'\')">  
 </a>';
