Editable textbox with text from switch statement.

Question

I'm trying to make form that has text fields that get pre-populated based upon dropdown choices. I tried to use else/if statements, but I was advised to use a switch statement.  The problem is that I NEED the end-user to be able to make changes to the textbox that is created/generated from the switch statement.  For example I have the code below.  It will switch the text in the textbox perfectly when I choose different items in the AddtlServicesDrop1 box.  But I need the end-user to be able to add more info to the "promotes roots" text....but everytime I type text into the box it disappears when a new cell/item is clicked.  Can anybody give me some help? 
//Custom Calculate script 
(function () { 
    var Description1 = getField("AddtlServicesDrop1").value; 
    switch (Description1) { 
    case "Soil Test" : event.value = "To apply the right kind and amount of fertilizer. I need to test your soil. Our soil test will determine pH and nutrient needs (lime, sulfur, phosphorus, & potassium)."; break; 
    case "Heavy Core Aeration": event.value = "Promotes roots"; break; 
    case "Seeding": event.value = "Thin spots"; break; 
    case "Lawn Disease Control Program" : event.value = "Prevent Disease"; break; 
    case "Perimeter Pest Control": event.value = "Prevent Ants"; break; 
    default: event.value = "";

Use equals instead of ==
String temp = textFieldCountry.getText();
if (temp .equals("Netherlands"))
return true;
else
return false;
