First of all, remove that file from here, if you do not want to hear from the moderators, posting a vb file here is against your license terms.
Second, check your code and find:
PHP Code:
if($invBChat == ""){
$invBChat = "<i>No one is currently inside vBChat</i>";
Replace that with
PHP Code:
if($invBChat == ""){
$invBChat = "<i>No one is currently inside vBChat</i>";
}
I think you missed a curly bracket there.
