Team Calendar 2.0

I downloaded the outlook 2k team calendar 2.0 as suggested in this tech republic article: https://www.techrepublic.com/article.jhtml?id=r00320010319knm02.htm&fromtm=e012
It seemed to install fine, but when I try to open it I get the following error:
Internet Explorer Script Error - an error has occurred in the script on this page.
Line: 938 (tends to vary)
Char: 2
Error: Type mismatch: 'UBound'
Code: 0
URL file://C:\Office 2000\teamcalendar\teamcal.htm
Do you want to continue running scripts on this page? Y/N
Does anyone know of what might be causing this? We run Exchange 5.5 sp4 on a NT 4.0 sp6 server and Outlook 2k sr1/sp2 on w2k pro workstation. The email is stored locally on a .pst file. Thanks!
