Tab Content Script (Sub Tabs) Help

[pittstop computers]

1) Script Title: Tab Content Script

2) Script URL (on DD): http://www.dynamicdrive.com/dynamici...tabcontent.htm

3) Describe problem: I am trying to have tabs within tabs. So that when for instance tab #3 is clicked it has 2 tabs that are in tab#3 only. I have this working almost 100% in FF and Safari, but IE7 wont allow me to click the second sub-tab. There are a couple other minor issues I am having as well, and if anyone can help me, I would greatly appreciate it. If you need any code or links to my tabs page, please ask. Thanks so much!
