PS03 - PWA - Tasks Error

[ControlZ]

I've got a new error, but maybe someone here has seen it before.

I have a user who cannot see the Tasks page on PWA. All of the other
pages work just fine. It freezes on loading data and there's an error
in the bottom left corner of the web browser.

The error says:
line: 5225
char: 6
error: type mismatch
code 0
URL: ht..../Tasks/TasksPage.asp

I can't find any errors on the server log event viewer.

Any tips? Suggestions? Places to look for more info?

Thanks.
