Calculate text fields based on listbox choice

The project is my first attempt at Java.

I have a PDF form with a (single select) listbox named "Type" the three options are "View," "Folder" or "Action." Based on the users choice in this list box I would like to change the contents of all three (risk) text fields "High," "Medium" and "Low." For example:

If the "Type" field ="View"
Then the: "High" field = "Outside of scope, change denied"
and "Medium" Field = "Complete remedial action and proceed with change"
and "Low" Field = "Proceed with change."

Else if "Type" field = "Folder"
then . . . text for three risk fields

Else if "Type" field = "Action"
then . . . text for three risk fields

Thanks in advance for all assistance.

I understand the question like this:

var optVal = new Array();
optVal["View"] = [
"Outside of scope, change denied",
"Complete remedial action and proceed with change",
"Proceed with change."];
optVal["Folder"] = [
"High Folder Risk",
"Medium Folder Risk",
"Low Folder Risk"];
optVal["Action"] = [
"High Action Risk",
"Medium Action Risk",
"Low Action Risk"];

function setChoice(theSel){
  selVal = theSel.value;
  theForm = theSel.form;
  theForm.High.value = optVal[selVal][0];
  theForm.Medium.value = optVal[selVal][1];
  theForm.Low.value = optVal[selVal][2];
<body onLoad="setChoice(document.forms[0].Type)">
<select name="Type" onChange="setChoice(this)">
<option value="View" SELECTED>View
<option value="Folder">Folder
<option value="Action">Action
<input type=text name="High"><br>
<input type=text name="Medium"><br>
<input type=text name="Low">

This is a PDF form with text fields that I would like to calculate using a javascript.

Zvonko, does my untrained eye see html tags in your script?

I am looking for a custom validation script to place in the javascript editor for the "Medium" text field. The result of the script is to display three different text strings based on the choice in the "Type" listbox. A user dialog or prompt is not necessary. The form has multiple fields that the user will complete, one of them is "Type."

If "Type" = "View" then "Medium"= "Look-ups exist and have been indentified."

If "Type" =  "Action" then "Medium" = "Not applicable for actions."

If "Type" =  "Form" then "Medium" = "Moving fields, changing fields names or changing data types."

I will attempt to modify a working script for placement in the Low and High fields.

Thanks for any assistance,
