Error entering new record on a subform

[AccessNewb11]

Hi all!
I am having a problem with my Contacts Database. I have attached it for your review.
On my main form entitled "frmContact", I have a form to enter a new contact. I have a Notes subform, and I want to be able to enter multiple notes for one person. I have a note for John Doe, and tried to enter a new note for him and got this error message:

"The LinkMasterFields property setting has produced this error: 'The object doesn't contain the Automation object 'tblcontact"."

Please help!
Thank you so much in advance!

It's possible in your relationships is in error. You currently have COMPANY and CONTACT in a 1 to 1 relationship. Which means only 1 person per company.
Its possible 2 people could work for the same company and may cause validation error.

I tend not to use these kind of relationships..ONLY vital ones like:

tOrder - tOrderItems
or
tPerson - tPersonPhones

...the 1 to many tables rels. that MUST exist.
