[Javascript] String -> Number impossible

[Peter Brunone]

		What leads you to believe that it is a string, even after parseFloat?

> total = total+(array_prices[i])*(2);// this value works here, but I

    I'm curious about this... you're assigning the array elements as strings (i.e. with quotes) rather than as integers.

Hi list,

First forgive me for posting code up in the email, there's no online
page that I can show the script.
I'm having a terrible, like 2 hours wasted on this terrible error,
trying to figure this out:
Here's the code:

array_prices = new Array();
array_prices[1] = '115'; //these values are coming from a db
array_prices[2] = '95';

function getCheckedValue(radioObj) {
	var radioLength = radioObj.length;
	for(var i = 0; i < radioLength; i++) {
		if(radioObj[i].checked) {
		return radioObj[i].value;
		}
	}
}

function updateTotal(){
	total = 0;
	totalField = document.getElementById('valorOnlyNumber');
	for (i=1; i < array_prices.length; i++){
		total = total+(array_prices[i])*(2);// this value works here, but I
hardcoded it
	}
	rdVal = getCheckedValue(document.frm_calcShipping.valFrete);
	if (rdVal != 0){
		total = total+rdVal;
	}
	totalField.innerHTML = total;
}

and these are my radios:

name="valFrete" />R$ 6,70

name="valFrete" />R$ 7,20

name="valFrete" />R$ 12,60

name="valFrete" />R$ 18,60

R$ 210.00

+++++++++++++++++++++
The problem is that rdVal is always a string, I've tried

rdVal = parseFloat('getCheckedValue(document.frm_calcShipping.valFrete)')

still a string

I can't figure out what to do please someone advice

TIA
Marcelo
