I have a cascading drop-down
When I select Value from drop-down based on values I need to update the description filed automatically.
For example I select A from first drop down and B from second drop down i need to update description relate to this condition.
Similarly if I select A from first drop down and C from second drop down I need to update description related to this condition.
Like wise if I select X from first drop down and Y from second drop down I need to update description related to this condition
How can this be achieved . Please help
