Project 2007 Enterprise standard calendar question

[Lily]

When I perform the following I get a message that I don't understand.
File, open, select template to save as, rename the template, click save.
Microsoft Office Project box appears.
Enterprise standard calendars are needed.
Enterprise standard calendars are required to:
Build a team for a non-enterprise project
Save a non-enterprise project
Import resources to the enterprise

This may result in changes to schedule dates. Do you want to continue?
Yes No
Does anyone know what the choices mean? What will occur if I choose yes or no?

When you save a plan to the server, the standard calendar on your local plan
will be replaced with the standard calendar from the server. The calendars
could be different and this will cause schedule changes in your plan.

If you click Yes, the plan will be loaded to the server and the calendar
will be replaced with the server version and the schedule might change to
accommodate the calendar differences.

If you click No, the plan will not be saved.
