59634 Webmail Script Error Needs Fix

I have a webmail CGI script from "Curly Mail" ([login to view URL]) that has an Error in the coding that needs repair. On the "Address" page, it is Not able to Compose after hitting button the (To:) field into Poping-Up an email page?? Seems like the page is showing an error. Please go here ([login to view URL]) and signup for a free account and test out everything to see where that error on that Address page is coming from. Then get back to me with your quote to fix this minor problem. Would appreciate. Payment in full after 100% completion of work to my saticfaction. Payment through SL escrow or PayPal only. Thanks....
