Hey
I'm trying to create an aggregates calculator where the sum & average are calculated from the user inputs textarea of values, which i have split(). This is my code so far. I'm sure I'm not using the variables or parseFloat method correctly.
Any advise?
Many Thanks

<script type="text/javascript">
<!--
function add()
{
document.getElementById("answer").value+=(document.getElementById("num1").value) + '\n';
}
function calculate()
{
var total = "sa";
var sa = textAreaText.split("\n");
for (var i=0; i < sa.length; i++)
parseFloat(sa[i]) + total;
{
document.getElementById("sum").value = total;
}
{
document.getElementById("average").value = total / sa.length;
}
}
