CoachDirectories

I recently added a javascript button from my web components on Microsoft frontage / Why frontage? Beginner designer. Have dreamweaver but not accustomed to program yet. Anyway I have tried to view the website on multiple computers but each one asked you to upload or update java. Is there anyway to by pass this or did I forget to add an applet. can someone provide me with some instruction? I have been teaching myself this program and such. please help? ref: coachdirectories.com
