Choose JavaScript script to executed from a combo box.

Hello,

I'm having the following little problem, and i'm hoping that someone here can help me solve it.

I created an combo box in Acrobat professional 8.1.

The combo box gives the user 4 different choices to choose from, and does not
allow any other user input in the combo box.

The export values of the 4 choices are "Item01", Item02", "Item03" and "Item04".

What i would like to have is a JavaScript that executes the JavaScript "JS_Item01",
when the choice with export value "Item01" is chosen.

When the choice with export value "Item02" is chosen, a JavaScript named "JS_Item02"
should be executed.

The same procedure has to apply for the export values "Item03" and "Item04".

Is there an easy way to do this. ?

Thanks,
