It seems that your problem is that you don't cast your strings as int. + can mean either concatenation or addition, depending on the types of the 2 variables it's used on.
For example:
var x = '1';
var y = 2;
alert(x+y); // 12, since x is a string and y is automatically cast to string.
alert(parseInt(x)+parseInt(y)) = 3; // since we cast both x and y to int.
PS: If you really need help, and for anyone here to read your code, copy the important bits, not the whole file.
PS2: You should start using jQuery - it can save you a lot of time

How to Insert Multiple row into database

this is my code .. My problem is when I create multiple row, only the first row only make it into the database .. The next row is not .. For your information, add row function works well... I use the concept of MVC
View
<SCRIPT language="javascript">
function addRow(tableID) {
var table = document.getElementById(tableID);
var rowCount = table.rows.length;
var row = table.insertRow(rowCount);

You don't need to add special ids.
1.) First change the id to a class:
From: <div id="companydiv"><input name="company" value="" /></div>
To: <div class="companydiv"><input name="company" value="" /></div>
2.) Change the select onchange parameter to this:
From: <select name="product" onChange="getcompany(this.value)">
To: <select name="product" onChange="getcompany(this)">
3.) Replace your getcompany function with:
function getcompany(element) { // the parametername has changed
var strURL="getcompany.php?product="+element.value; // this line has changed
var req = getXMLHTTP();
if (req) {
req.onreadystatechange = function() {
if (req.readyState == 4) {
// only if "OK"
if (req.status == 200) {
// last changes here:
element.parentNode.parentNode.getElementsByClassName('companydiv')[0].innerHTML=req.responseText;
} else {
alert("There was a problem while using XMLHTTP:\n" + req.statusText);
}
}
}
req.open("GET", strURL, true);
req.send(null);
}
}
I see from your page that you use the same ids companyDiv for all new rows. This will be an issue.
See this line in your getCompany success method
document.getElementById('companydiv').innerHTML=req.responseText
Edit
When you add new rows, try giving an id based on the index number of this row. That way, in your <select name="product" onChange="getcompany(this.value)"> onchange method, you can exactly get the div that you are searching for
Edit 2
In your addRow method, check this line var row = table.insertRow(rowCount);
Now to change the id of this row, all you have to do is, (provided your first row has an id '1')
row.id = 'aNewId' + (parseInt(row.nextSibling.id) + 1);
ar=array("product1"=>"company1", "product2"=>"company2");
var str="";
$("#productSelectorId").change(function () {
$("select option:selected").each(function () {
str += $(this).text() + " ";
});
$("#companySelectorId").text(ar[str]);
}).change();
