[SOLVED] NaN and Undefined in Javascript

[ainoy31]

Hello-

 

I have a form the calculates the total dimension weight and chargeable weight.  However, these two fields are calculated base on what is entered prior.  So, as I enter my measurements, in the total dimension and chargeable fields I see NaN and undefined pop up.  However, once I finish entering all my measurements, NaN and undefined goes away and displays the correct results.  Does anyone know a fix for this?  Much appreciation.  AM

Nevermind.  I fixed my issue.  The problem was that I was passing in the var result where I am calculating the total.  First, I needed to check to see is the var result was null or not.  If is was, I need to set my total dimension value to 0.

 

if(result == null)

{

document.getElementById('tot_dim').value = '';

....and so on.

 

}
