I have a form that is used to update trainees.
On this form I have a couple of drop down.
The drop downs each have a predefined list of choices.
I have enable "Append choices to lookup".
My goal is to update a trainees information for example:

Drop down for "Socio Economic Status" has to lists choices of employed & unemployed.

When the trainee gets registered first his socio economic status might be "unemployed".

Now I want to update the trainees details and change it to "employed" but I want the drop down field to be populated from the data source and read "Unemployed"

I then want to be able to click on the drop down and select "employed" as the new status.

Currently the drop down is just blank but I have an option to either select employed or not employed.

Is there a way to use the first result returned from the appended lookup as the default value?

Please see attached images for further explanation.
