popup alert onchange

I have a form with a number of text boxes for prices. I'm trying to write a javascript function that will pop up a alert if the price entered is 0.00. I want to use the onchange event on the text boxes. This is what I wrote so far but I'm totally new to javascript so hopefully my code isn't too horribly wrong.

<script type="text/javascript">

Function CheckZeroValue(x)
{
var y = document.getElementById(x).value

If y == "0.00"{
alert("Are you sure?");
}
}
</script>

<input type="text" id="Price1" onchange=CheckZeroValue(this.id)">

When I run this I get an "object expected" error.

Please help!

<script type="text/javascript">
 
Function CheckZeroValue(x) {

If (x == "0.00") {

    alert("Are you sure?");

}

}

</script>
 
<input type="text" id="Price1" onchange=CheckZeroValue(this.value)">

this should fix you up.

Thank you for your reply and your help .. but I'm still getting an Object Expected error. This is the test page I built exactly ..

<html>
<head>

<script type="text/javascript">

function CheckZeroValue(x) {

If (x == "0.00") {
alert("Are you Sure?");
}
}

</script>

</head>
<body>

Price: <input type="text" id="Price1"
onchange="CheckZeroValue(this.value)">

</body>
</html>

the only problem i´ve noticed in your code is the way you wrote "if" ehehe

its written "If" and should be "if"
just fix that and you code will be ok :)
