I have recently come across the problem of using edate, eomonth, etc. in my
excel spread sheet. Anytime I change the start date argument or duartion
argument, it comes up with #NAME? and have to uninstall the add-ins and
reinstall them to get the formulas to work again. This has only happened
after the installation of Office SP2. Is there an update that will remedy
this problem.

Thanks.
