In a page, I have a table with user entering field.
There are 4 fields, first three are user entering fields and the fourth field is auto calculating of the first three fields,if the user leaves a field the total field showing NaN. How to solve this problem?

Once again Antony, you lead off without showing your code. It seems we have to pry it out of you. Please, pretty please with sprinkles on top: show your code - you're more likely to get help. Describing the form says nothing. Where's the js? Ah, it's up to us to guess? Sorry if that sounds a bit sarcastic, but we really need to sort this out.

function calcTotal(a,i,j)
{
    c = parseInt(a);
    h = document.getElementById('Hvalue'+i).value;
    document.getElementById('Hvalue'+i).value = c;
    d = parseInt(h)+parseInt(a);
    document.getElementById('Hvalue'+i).value = d;

    document.getElementById('total'+i).value =  d;

    document.getElementById('stuid'+j).readOnly = true; 
}

Not sure what this is supposed to be doing.

Surely you just need to add the values?

Show your markup too. This is trying to get blood out of a stone Antony. Patience is a virtue but I'm running on empty.
