adding totals from 1 array to another

[Mark Scott]

I am trying to add some totals from one array into another and clearing down
the first array. When I run the following code, I get "undefined" rather
than the totals?

Also, the loop:

for (counter = 0; counter < productStock.length; counter = counter + 1)
{
document.write("The counter variable is: "+counter+"<BR>")
productStock[counter] = productStock[counter] + receivedLevels[counter]
receivedLevels[counter] = 0
document.write(productStock[counter]+"<BR>")
}

Doesnt appear to fire.

Regards

Mark

do you know what you're doing when you code that line bellow ?

productStock = parseFloat(productStock)

You can parseFloat a string but certainly not an array

<http://developer.mozilla.org/en/docs/Core_JavaScript_1.5_Reference:Global_Functions:parseFloat>
<http://www.w3schools.com/jsref/jsref_parseFloat.asp>

suppress these two parseFloat ans all will be OK

receivedLevels = parseFloat(receivedLevels)
for (counter = 0; counter < productStock.length; counter = counter + 1)
{
document.write("The counter variable is: "+counter+"<BR>")
productStock[counter] = productStock[counter] + receivedLevels[counter]
receivedLevels[counter] = 0
document.write(productStock[counter]+"<BR>")
}
document.write(productStock[0]+"<BR>");
document.write(productStock[1]+"<BR>");
document.write(productStock[2]+"<BR>");
document.write(productStock[3]+"<BR>");
document.write(productStock[4]+"<BR>");
document.write(productStock[5]+"<BR>");
}
addAllReceivedItems()
