How can I calculate the value of a custom field every time another field is updated?

[Claus Kolb]

Dear all,

I would like to change the value of a numeric custom field of a Story every time the fields Original Estimate or Remaining Estimate of a Sub-Task are updated. Do you have an idea how I could achieve this?

Best regards
