Hi all,
How would I implement a dynamic calculation with the field calculator? With 
dynamic I mean that the result would change as values change in the input 
fields. With a Shape file, the result field obviously only contains the 
numerical result of any calculation and when the input changes I have to retype 
and re-execute the calculation in the field  calculator.
In other GIS-Systems I have used this would be called a query.

Thanks for any input on this.
Peter
