I have a calculation field that basically divides the total labor rate by the pieces made per hour to come up with the labor rate of producing a product. In another occurrence of the same table that field is in I can make changes to the labor rate and want that change to also occur in the calculation field. This does change but only if you actually select the calculation field. My database is used in filemaker server so making the labor rate field global will not work. Is there a way to make the changes occur in the calculation field without a looping script?
