install on PHPBB help!

[Ryan009]

Disclaimer - I am extremely new to running a forum!

I've had PHPBB 3.0X up and running for about 2 months now. I got a request for a chat room so I decided to try 123.

I manually made all the changes per the instructions (actually did it twice) but I keep having problems.

As soon as I get to modifying the index.php file per following instuctions:
Open File:
root/index.php

Find:
$birthday_list = '';

After add:
// begin 123 flash chat mod
include($phpbb_root_path . 'includes/functions_chat.'.$phpEx);
$chat_info = getChatters();
$chat_list = getChatterList();
//end 123 flash chat mod
CODE: SELECT ALL
Open File:
root/index.php

Find:
'TOTAL_USERS' => sprintf($user->lang[$l_total_user_s], $total_users),

After add:
// begin 123 flash chat mod
'CHAT_TOTAL_ROOMS' => $chat_info['room_numbers'],
'CHAT_TOTAL_CONNECTIONS' => $chat_info['connections'],
'CHAT_TOTAL_LOGON_USERS' => $chat_info['logon_users'],
'CHAT_USER_LIST' => $chat_list,
'CHAT_WIDTH' => $config['chat_width'],
'CHAT_HEIGHT' => $config['chat_height'],
//end 123 flash chat mod

I can no longer load the site. It downloads the following error:
<br />
<b>Fatal error</b>: Call to undefined function getchatters() in <b>/home/XXXXXX/public_html/test/index.php</b> on line <b>86</b><br />

So I tried putting the index file back to its original state (worked fine) and tried continuing with the MOD thinking I would come back to it.

The MOD installs fine through the ACP, but whenever I try to select the 123chat MOD tab, I get this:
Return to the index page
General Error
Language file ./../language/en_us/mods/chat.php couldn't be opened.
Please notify the board administrator or webmaster: XXXXXXX

What am I doing wrong? I triple checked that I uploaded all the correct files to the correct locations?

The possible reason that the chat module is not loaded properly is that the language file is not copied correctly.

In module,the file is at /root/language/en/mods/chat.php,it seems you're using en_us as your default language,so just copy file /root/language/en/mods/chat.php to /root/language/en_us/mods/chat.php and try to load the chat_acp in admin panel again.
