a novice with html could use a little help !!!!

Hey guys I was wondering if anyone knew how to create a currency converter using html programming, here are the guidelines I am looking for :

Develop an HTML/JavaScript program that creates a web page that can be used as a GUI to convert U.S. currency to Canadian dollars, British Pound, or Euro. The conversion formulas are:

1 US $ = 0.974 Canadian Dollar
1 US $ = 0.492 British Pound
1 US $ = 0.706 Euro

program should be able to convert values of $100 million or more.

Thanks for all the help I really appreciate it

here is what I have so far

[HTML]<!Currency Converter-->
<Html>
<head>
<title> Currency Converter</title>
<script language="javascript">
function convert(){
if (document.conversions.choice[0].checked){
var result= eval(document.conversions.degree.value*1=0.974);
document.conversions.convertedvalue.value=result;
var inputunit= "US Dollar";
document.conversions.inUnit.value= inputUnit;
var outputUnit="Canadian Dollar";
document.conversions.outUnit.value=outputUnit;
}//end if

<Body background="blue">
<form name = "Conversions">
<table border=6bgcolor="red">
<tr>
<td><font color="black"size=6>Enter Us dollar amount;</font>
<td><input type="text" name= "Dollar" size=4>
<td><input type="text" name= "Inunit" size= 20>
</tr>[/HTML]

Please try to use code tags when including code. I makes it much easier to read.

A couple of issues I see.

1. The convert function does not seem to ever be called any where. What is supposed to trigger that function?

2. There is an IF test checking the checked attribute, but I do not see a check box in your code? Is there HTML that was not included? If not it is never going to get passed that test.

3. There is JavaScript accessing an input tag named outUnit, but I do not see that field anywhere in the HTML.

4. It is usually faster and more reliable to refernce tags by their ID attribute rather than using them DOM tree path.

So to access :

[HTML]<input type="text" id="dallor" name= "Dollar" size=4>[/HTML]

It would be better to do this.

Expand|Select|Wrap|Line Numbers

document.getElementIdBy('dallor');
