Each of the boxes shown in your Relationships tab are called Tutorial: What are Table Occurrences?. Only one of these may be selected in Layout Setup | Show Records from for a given layout. Which one did you select?
The table occurrence you select in that drop down then determines which table occurrences are related and which are unrelated. When you add a field to your layout and the specify fields dialog opens. The "table" that you select from the drop down is actually one of these table occurrences.
Thus, if you are seeing "Unrelated Table" the field was selected from a table occurrence that is not linked (either directly or indirectly) to the table occurrence specified for your layout.
Thanks again for your help.
RMAnumber and SerialNumber all come from Company_RMA_fk
In my attempt to get this two new field in those table occurances you allude to, Company_RAM_fk is NOT a selection! Why would that be?
To repeat: On what table occurrence is your layout based?
RMA, and I see where I made the mistake, I put it in the WRONG TABLE! I have corrected it and it works!!!
Thanks for the Guidance! Greatly appreciated. :) Problem solved.
Glad it's working but there is no table occurrence named RMA in your screen shot.
Apologies, this is an RMA report I am enhancing. The TO is Company_RMA_fk, 6th table in the diagram above.
