Get cells by className to equal innerHTML of cell id ‘subtotal’

I’m trying to grab all the cells created with insertrow function and the className ‘rowtotal’ and get their innerHTML to equal that of a cell with id ‘subtotal’. This is a simplified html code of single cell inserted rows:

[U][B]index.html[/B][/U]

[code=html]
<tfoot> <tr id=”footsubtotal”> <td id=”subtotal”>$ 75.00</td>
//all cells of class “rowsubtotal” must have same innerHTML as this.
</tr>
</tfoot>
<tbody>
<tr class=”itemrow”>
<td class=”rowsubtotal”>$ 15.00</td>
</tr>
<!–3rd inserted row at row index 0 innerHTML should be ‘$ 75.00’–>
<tr class=”itemrow”>
<td class=”rowsubtotal”>$ 20.00</td>
</tr>
<!–2nd inserted row at row index 0 innerHTML should be ‘$ 75.00’–>
<tr class=”itemrow”>
<td class=”rowsubtotal”>$ 40.00</td>
</tr>
<!–1st inserted row at row index 0 innerHTML should be ‘$ 75.00’–>
<tr class=”dummy”>
<td class=”message”>Thank You</td>
</tr>
</tbody>

[/code]

These functions are not working and I’m not sure I can get javascript functions that will.

[U][B]product.js[/B][/U]

[CODE]
function checksubtotal(){
var subtotal=document.getElementById(‘subtotal’).innerHTML;
var rowsubtotals=document.getElementsByClassName(‘rowsubtotal’);
for(var i=0; i< rowsubtotals.length; i++){
var rowsubtotal=rowsubtotals[i];
if(rowsubtotal.innerHTML!==subtotal){ //comparison ‘!==’ ???
rowsubtotal.innerHTML=subtotal; }
else{ rowsubtotal.innerHTML=subtotal; }}//throws syntax error?

function deleterow(a) { // remove row
var row=a.parentNode.parentNode;
row.parentNode.removeChild(row);
var sTotal=sumsubtotal();
//don’t know what this is but seems to work??
EvalSound4(); checksubtotal();
//doesn’t work??

[/code]

Not sure if this is the wrong approach, might have to use a
!match syntax. Any help greatly appreciated?
