Javascript acting different

[blackcell]

I am looking for possibilities that may cause a problem for me. Here is the situation:

 

PC1 is running FF3B5

PC2 is running FF3B5 <---The same as PC1

 

I have a javascript popup calendar that will allow you to click an icon. Once you do this a calendar pops up allowing you to select a date. When the date is selected it will put that date in a standard format.

 

This works on PC1 but does not work on PC2 whenever they are on the same exact page using the same exact calendar?

 

What gives?

Are both machines viewing the page with the same kind of browser?

Yep, sorry FF3B5 is Firefox 3 Beta 5. I think it may have something to do with plugins because my boss jacked with his until he had it working but he said he couldn't really tell what exactly made it work. So I don't know but I would like to know how to correct the problem in the future because this makes twice this quirky problem has happened.
