Substitute ( Causes ; ¶ ; ", " ) as calulated field, and merge that instead of "Causes"
This could very well be correct, but I don't understand what you are asking me to do. Can you elaborate?
You can create another field CausesDisplay. It is an autoEnter or a calculation field and you use the formula above.
CausesDisplay = Substitute ( Causes ; ¶ ; ", " )
Then put CausesDisplay on your other layout to display the data. In FileMake the carriage return is shown and manupulated as the the pilcrow character eg -> ¶
Your are finding all the carriage returns and replacing them with a comma and a space so they stay on the line.
