I am new at developing Filemaker although I have used it in the past for data entry. I have designed my tables / Fields everything was good except when I opened my filemaker database this morning it was showing " unrelated Table" in all of my fields. Please tell me what happened. or a few suggestions as to how I may fix this. I really do not want to redesign my layouts as they are quite extensive. Thanks in advance.

A layout is based on a table occurrence. A table occurrence represents a table in your file. Fields on a layout need to be either in the table upon which the layout is based or from a related table occurrence.

If you describe one of your layouts, we'd be happy to use specifics.
