Bug fixes for custom php/ajax private message script

I need help with a private message script that is installed in one of our oscommerce sites. The private message script is mainly php/jquery/ajax script. There are 3 script pages in the catalog side, and 3 script pages in the admin side. Not a big script to work on and is fairly easy to understand. There is a couple of immediate problems I need fixed, these are described below: 1. When sending a private message from oscommerce catalog side using internet explorer, the message recieved at oscommerce admin side is blank. (If you use Firefox, the message is received) 2. When trying to send a private message from oscommerce catalog side using google chrome, the input text message box is not available. (The input text message box is available in internet explorer and fixefox though) 3. When 1 & 2 are complete, I will test private messages in google chrome, internet explorer and fireworks for bugs. If I find more bugs you will be required to fix these too. I can help as much as possible, I will tell you where all the files are in which folders, and what code lines I think may be the problem. I would only like bids from experts with ajax/jquery/php who will understand this script almost right away and know how to fix it. I have a good idea how long it will take an expert to fix these bugs and I will not pay for someone to first learn what the script does then try to fix it.
