Validation script on dropdown list field depended on other dropdown list

[Mr. SOTHON]

Hi, anyone can help me to make this happen? field#1 dropdown list is group like (Fruit) and field#2 dropdown list is type of fruit. I have many pages kind of fruit and I want to select feild#1 dropdown list it show kind of field #2. I tried many time but it seem error while we select group field#1 again it only go to page.

I tried following code from peoeple here in validation field#2 in Run Custom validation script as following: 

if(event.value == "apple") this.pageNum = 1;
else if(event.value == "banana") this.pageNum = 2;

any Error in above scrip? Or any suggestion beside make validation script?

The script is OK. 

[Mr. SOTHON]

Yep the script is running well if dropdown list field#2 is independent. Any idea make this dependency to dropdown list field#1? I tried make it denpendency but seem not working while I tried to click field#1 it going to page all time. In short, I can't select field#1.

What script does you use at field#1?

IMPORTANT!

Edit the following line to identify the field name of the dependent list box then edit the properties of the dependentListValues JSON object. Property names should correspond to the export values of the list items.

var dependentListBoxFieldName = "article";

var dependentListValues = 

{

"Friuit": [

["Apple"],

var dependentListBoxFieldName = "article";
var dependentListValues = 
{
"Friuit": [
["Apple"],

This script makes no sense.

[Mr. SOTHON]
