Getting a null value for last choice row in slider question

Hi,



I'm trying to simply grab the choice values from a slider question in javascript. I have 8 rows/choices in the question and I'm able to grab the first 7 rows, but for some reason, I'm unable to get the last row.



var food_Cereal = this.getChoiceValue(1);

var food_Pulses = this.getChoiceValue(2);

var food_Veg = this.getChoiceValue(3);

var food_Fruit = this.getChoiceValue(4);

var food_Meat = this.getChoiceValue(5);

var food_Milk = this.getChoiceValue(6);

var food_Sugar = this.getChoiceValue(7);

var food_Oil = this.getChoiceValue(8);



alert("TEST: Cereal and Tubers: " + food_Cereal);

alert("TEST: Pulses: " + food_Pulses);

alert("TEST: Vegetables: " + food_Veg);

alert("TEST: Fruit: " + food_Fruit);

alert("TEST: Meat: " + food_Meat);

alert("TEST: Milk: " + food_Milk);

alert("TEST: Sugar: " + food_Sugar);

alert("TEST: Oil: " + food_Oil); --> always returns NULL



Has anyone encountered this?

I know its not out of range, because it would otherwise return "undefined".



Thanks,

Anthony
