Dotnetnuke Survey module viewed on Blackberry - Troubleshooting help needed!

Hi I'm running the dotnetnuke survey module on the latest version of dotnetnuke. The module works fine on a desktop pc, laptop, iphone, and a blackberry. However, my client who needs to use this app cannot get it to work on his or his collegues blackberries. They keep getting a javascript error. I think this error is a result of my client using a blackberry in conjunction with the blackberry enterprise server. I've tried adjusting all the settings on the blackberry itself but it still doesn't work. As such, I'll like to pay someone to troubleshoot this issue for me and provide instructions on how to fix this. The website that the survey app is on is www.telusvotes.com. It's written in asp.net thx Brad
