Need help with simple price x quantity calculation

[brossyg]

I have a very simple price times quantity calculation.

The input is STWCORQuant:

<input name="STWCORQuant" class="contactitalicbold" id="STWCORQuant" onChange="javascript:STWCORPrice();" value="0" size="8" style="text-align: right; font-family: ver">

And the fucntion is STWCORPrice():

<script language="javascript" type="text/javascript">
 
function STWCORPrice() {
        var price = 0;
        var shipping = 0;
        var total=0;
        var qnty=document.all.STWCORQuant.value;
 
        if (qnty > 49 && qnty < 75){
                    price = 23;
                    shipping = 6.25;
                    }
 
                else if (qnty > 74 && qnty < 100){
                    price = 17;
                    shipping = 6.25;
                        }
 
                else if (qnty > 99 && qnty < 200){
                    price = 14;
                    shipping = 6.25;
                        }
 
                else if (qnty > 199 && qnty < 250){
                    price = 13.75;
                    shipping = 7.75;
                        }
 
        total = (price * qnty)+shipping;        
        document.all.STWCORIssueCost.value= '$ '+ total.toFixed(2);
    }
 
</script>
 

The output is this:

<td width="15%" id="STWCORIssueCost" Font Class="sidemenutextgrn" align="right">$0</Font></td>

It doesn't work, but looks like it should. When a quantity is input and the box is tabbed out of, nothing happens. I can't tell what is wrong....need help!

Thanks

I think, node.nodeValue should work also.

Actually, it wouldn't. You'd need to use firstChild.node Value in place of innerHTML.

you're right, I forgot the child status of the text node.....
