Exporting and importing a sub form in Access 2007

I tried to export then import a subform into Access 2007. When I export it is
fine but when I try to import a get the following message:

The module name 'Form_Search_ServiceOrders' is invalide.

* The module name may start with the prefic Form_ or Report_.
* The module name can be named Forms, Reports, Modules, Application, Screen,
Assistant, CommandBars, References, or DoCmd.
* The module name may have to many characters.

I tried to rename the exported file but that did not work. The name seems to
fit the naming scheme. Is there anything special I should do when exporting
or importing. I need help to figure out what is going on with this.
