I have a field called "class" which uses the case function given age and sex of a livestock to determine its category: calf, heifer, cow, bull and so on. With time as the animal is growing it will be changing its category status; say from calf -> heifer -> cow etc.
This works Ok and I am happy with it. What I want is for this field to trigger change in the drop down list based on value list based on a Category table that has same values that a result of the class calculation. In other words if class = "cow", then script trigger must category drop down list to select "cow" automatically.
