Using Variable When Reading Value From ASP Array

I need to use a javascript variable when reading a value from a asp array. Currently I have a windows app that has a webbrowser. The windows app invokes a javascript method through the webbrowser and this javascript method returns an object. This object is built in the javascript function using values which exist inside a classic asp array. The function that sits on the relevant asp page, is invoked from my windows app and then returns the object to the windows app is below.

function item(count){
var pid;
var description;
var fullprice;
var discountprice;
var quantity;
var size;

this.pid = '<%=SBagArray(0,count) %>'; //ProductId
this.description = "<%=SBagArray(1,count)%>"; //description
this.fullprice = <%=SBagArray(8,count) %>; //Fullprice
this.discountprice = <%=SBagArray(9,count) %>; //Discountprice
this.quantity = <%=SBagArray(6,count) %>; //Quantity
this.size = <%=SBagArray(2,count) %>; //Size
this.getPid = function() { return this.pid; }
this.getDescription = function() { return this.description; }
this.getFullprice = function() { return this.fullprice; }
this.getDiscountprice = function() { return this.discountprice; }
this.getQuantity = function() { return this.quantity; }
this.getSize = function() { return this.size; }
}

My problem is that the variable 'count' is not recognised by the asp. So, how can I use this variable in such a way that it works?
