Thanks Niall,
The format of date and time is fine. When I open the file up myself (in Adobe Professional, not Designer), the form looks great and when others who only have Reader can also see this form fine. For some reason, it's only people with Adobe Standard that don't see this field and this field only in the form. Btw, we are all running Adobe 7.0 currently, but have plans in the future (hopefully soon) to upgrade.
Thanks again.
Rowena
