How do I make values change using a sequential set of rules?

[JDFields]

I am trying to create a field in which the value changes dependent upon the
range of values in several other fields. I hae created rules for the display
field, but when values change in the data fields, the displayed value does
not change.

Did you also create "Conditions" on the rules?

Remember that the rules for a field trigger when the value in that field is
changed. So to update a display field based on values in a data field, you
need to put the rules into the data field.
