I have a database with a summary layout and added a new layout. For simplicity, I added the fields of the new layout to the summary table and added a button to access the new layout from the summary layout with a simple script of "Go to layout".
When one tried to enter data into the new layout fields, a filemaker error message showed up and read
"This record cannot be modified in this window because it is already being modified in a different window."
What went wrong? How do I fix it? Thank you for your response!
