Javascript Addition

I have the following piece of Javascript that I would like to perform a multiplication and ten addition equation. The Multiplication is working but not the addition. When it gets to the addition part it appends the figure to the other return.

<script>
function findSum(){
	var baseOne = document.getElementById('addon-28-custom-price[custom-price]').value;
	var myBox1 = document.getElementById('addon-28-custom-price[my-deductible]').value;	
	var myBox2 = document.getElementById('addon-28-custom-price[bicycle-liability]').value;
	var myBox2a = myBox2 != '' ? myBox2 : 0;
	//var myBox3 = document.getElementById('qty3').value;

	//var myBox3a = myBox3 != '' ? myBox3 : 1;

	var result = document.getElementById('result');	
	var myResult = (baseOne) * (myBox1) + (myBox2a);

	 document.getElementById('result').value = myResult;
}
</script>

Open in new window

So at this line (var myResult = (baseOne) * (myBox1) + (myBox2a);) the answer will print out something like: 482.45.50 instead of adding 482 and 45.50 together.

You have to use parse method as given below example.

var sum = parseInt(my_input1) + parseInt(my_input2);

Like Parsing methods for float and date are available. Please use as per your need.
