How can I fix this plugin?

I have a plugin that puts an image besides the users message to indicate his position on the forum. It doesn't work anymore. Any help is greatly appreciated.

Code:

avacweb_chat_config.message_hook.push(function(row, username, user_id, user) {
    var avs = {
        'Puppycheese123' : 'http://s16.postimage.org/y6am0lx8h/Admin.png',
        'Mattyice92' : 'http://s22.postimage.org/ntxrqsmxp/V_I_P.png',

    defaultAv = 'http://s10.postimage.org/54y4v15tx/Member.png';
    user.innerHTML = '<img class="chatavatar" src="' + (avs[username] || defaultAv) + '">' + user.innerHTML;
});

Hmm there shouldn't be an issue really. Have you cleared your cache?
Because when I first released 1.9 there was an issue with the hook system but I've since fixed it.
When viewing the 1.9 js it should have a time stamp of 5/5/14 18:04 ... If it doesn't you're viewing an old copy.

I found the issue it was a script conflicting with mine. My walkme script was causing a problem.

edit- well @Mr.Easybb found it!

LG I got it he had some Walk Me script that was interfering with the entire site really so he disabled that and it works now
