variable in a frame 1

I have a page with three frames on it(frNav,frMain and frOder). I have used this in the past with success but am failing on this attempt to retrieve the value of a textbox and pass it to a textbox in another frame. This script is in the <head> document in the frMain frame. Below is the script:

function calcnsend(prod_num, prod_rate){
quant=document.frmcalcnsend.prod_num.value;
totvalue=quant*prod_rate;
parent.frOrder.prod_id.value=totvalue;
}

Here is the form in the <body> of the same document in the frMain frame:

<form action="pricing.cfm" method="post" name="frmcalcnsend" id="frmcalcnsend">
<tr>
<td width="300">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;#Widget</td>
<td width="150" align="center">
<table width="150" cellspacing="0" cellpadding="0" border="0">
<tr>
<td width="30" align="right">$</td>
<td width="120" colspan="2" align="right1.20&nbsp;&nbsp;&nbsp;&nbsp;</td>
</tr>
</table>
</td>
<td><input type="text" name="a01a" size="5" onBlur="calcnsend('a01a','1.20');"></td>
</tr>
</form>

The frOrder frame has a textbox named a01a. Using the code above, when the onblur event is activated and a number is typed in the a01a textbox, it generates the error "document.frmcalcnsend.prod_num has no properties".

Any help would be appreciated.

Change:

quant=document.frmcalcnsend.prod_num.value;

...to:

quant=document.frmcalcnsend.elements[prod_num].value;

prod_num is a variable and cannot be used the way you had it.

'hope that helps.

Thanks,
I made the change and it is now telling me that .elements is null or not an object.

Any ideas?

Show me the code as you have it now.

Also, a valid work-around would be:

Code: 
function calcnsend([b]prod_numObj[/b], prod_rate){
quant=[b]prod_numObj[/b].value;
totvalue=quant*prod_rate;
parent.frOrder.prod_id.value=totvalue;
}

...

<form action="pricing.cfm" method="post" name="frmcalcnsend" id="frmcalcnsend">
<tr>
    <td width="300">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;#Widget</td>
    <td width="150" align="center">
    <table width="150" cellspacing="0" cellpadding="0" border="0">
        <tr>
        <td width="30" align="right">$</td>
        <td width="120" colspan="2" align="right1.20&nbsp;&nbsp;&nbsp;&nbsp;</td>
        </tr>
    </table>
    </td>
    <td><input type="text" name="a01a" size="5" onBlur="calcnsend([b]this[/b],'1.20');"></td>
</tr>
</form>

'hope that helps.

Sorry,
All works well now except it is concantenating the variable instead of adding them.

use: parseInt(variableName) or parseFloat(variableName) for quant and prod_rate (e.g., totvalue = parseFloat(quant)*parseFloat(prod_rate)). You might get away with not doing it for prod_rate if you send 1.2 as a parameter to the function instead of '1.20' (with quotes).

Sorry,
But it is still concantenating the values instead of adding them.

Show us the code as you have it so far.

It is the code from above:

function calcnsend(prod_numObj, prod_rate){
quant=prod_numObj.value;
totvalue=quant*prod_rate;
parent.frOrder.prod_id.value=totvalue;
}

...

<form action="pricing.cfm" method="post" name="frmcalcnsend" id="frmcalcnsend">
<tr>
<td width="300">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;#Widget</td>
<td width="150" align="center">
<table width="150" cellspacing="0" cellpadding="0" border="0">
<tr>
<td width="30" align="right">$</td>
<td width="120" colspan="2" align="right1.20&nbsp;&nbsp;&nbsp;&nbsp;</td>
</tr>
</table>
</td>
<td><input type="text" name="a01a" size="5" onBlur="calcnsend(this,'1.20');"></td>
</tr>
</form>

It's working fine for me in IE6 once I fix the typos in the above code. Is this a copy of your actual code?

<td width="120" colspan="2" align="right1.20&nbsp;&nbsp;&nbsp;&nbsp;</td>

...should be:
<td width="120" colspan="2" align="right">1.20&nbsp;&nbsp;&nbsp;&nbsp;</td>

Also, concatentation comes when two Strings are added together. You do not show any code with addition taking place. Is there additional code to see?

Fix that typo if it exists and post any other relevant code.

Thanks.

Sorry,
Not a complete list of the function:

function calcnsend(prod_num, prod_rate){
quant = document.frmcalcnsend.elements[prod_num].value;
totvalue=parseFloat(quant)*parseFloat(prod_rate);
parent.frOrder.orderlist.elements[prod_num].value=totvalue;
// total form
for(i=0;i<parent.frOrder.orderlist.elements.length;i++){
quantval=parseFloat(parent.frOrder.orderlist.elements.value);
totvalue1=(totvalue1+quantval);
}
parent.frOrder.orderlist.ordertotal.value=totvalue1;
}

Where do you declare totvalue1? My guess is, it reads something like:

var totvalue1 = '0';

If so, you need to change:

totvalue1=(totvalue1+quantval);

...to:

totvalue1=(parseFloat(totvalue1)+quantval);
