I have no idea what MS Dynamics CRM is.

If you use a template and people use the template to create a new document, the createdate is the date the new document is created. Savedate is a bit tricky in that the date is not updated until after the document is saved and may have to be manually updated depending on where in the document the field is kept. Simply saving the document is unlikely to update or change the field.

If it is working for you, there is no need to upload it. If not, try uploading along with a description of the problems you are having. Is it working?

If the source of your field is Paul's tutorial, refer to the section of the tutorial you used as a source.
