So you want the number value in a text field to be incremented when the user selects "2" from the dropdown? Is this correct.

If it is then enter this Validation script into the dropdown

if(event.value == 2)

     ++this.getField("Box").value;

When you are driving events from a dropdown, then the code that performs the action should be in one of the dropdown scripts that is activated on a selection. The Validation script is a good choice.
