The object doesn't contain the automation object 'opportunity_id''
I have a form that has a subform, which is throwing the above error. The subform has 2 tables it hits tbl_ClientOppJunction and tbl_Client, while the parent form hits the tbl_opportunity. I have set the "Master Link Field" to "tbl_Opportunity.Opportunity_Id" and the "Link Child Fields" to "Opportunity_Id". I can enter example data directly into the tables and it displays correctly, yet I can not enter it into the forms, I get the above error. I have searched the web on this and found some references to making the automated object available, but I am not sure how to do this since I am not using macros nor VBA code, just properties.
3 tables involved.
