Why do we get a NaN error when submitting in PWA?

[SteveP]

We are using MS Project 2007 SP1 and Project Web Access (IE 6.0)

We've used Project Professional for almost 3 years now, and have only
received this error less than a dozen times.

A user will update a percentage in the My Tasks section of PWA, and it
submits as if accepted. However, they show a "Not Accepted" message
in the % field. The Admin receives an e-mail as normal, but with
"Completion: NaN"....but the Admin can still approve the submission
in PWA and it updates Project Professional with the correct
percentage.

The only true issue we can find is that the PWA user does not think it
submits, and will submit it multiple times.

Any reason we would be getting this error?

Thank yuu

Steve

Correction - the message in the % field is "Not Done", it is incorrect
above as "Not Accepted"

Steve:

It sounds like you are tracking updates against milestones. You have to make
sure that your remaining work values are zero as well as marking the tasks
complete. When you assign resources to milestones, you can create work
values. Your best approach would be to add the remaining work field to the
My Tasks page and teach your resources to make sure that this is set to zero
when they mark the task complete, otherwise Project will show completion
while PWA shows not done. Also, you should upgrade your system to SP2 with
the latest CU patches. There have been fixes for milestone tracking in later
versions. You're way behind on maintaining your system if you're still
running on SP1.
