I am trying to write code that would allow me to have a list of products and it would be able to enter the amounts specified in boxes and give you the total once you press the total button....

I have pasted bellow what I have written so far... I am trying to figure out how to make it work... Please help me !

HTML4Strict Code:

<html>
<body>
<p>
 
 
Product 1<INPUT type="text" name="A" value=""
    onChange="A.value">
Product 2<INPUT type="text" name="B" value=""
    onChange="B.value">
 
 
<input type="submit" value="Total"> &nbsp; <input name="answer" type="text" size="4" maxlength="10"
onClick="document.calculator.ans.value+='A.value+B.value'">
 
    </p>
 
</body>
</html>

You have no form name to start with:

HTML4Strict Code:

<html>
<body>
<p>
 
<form name="Calculator">
Product 1<INPUT type="text" name="A" value=""
    onChange="A.value">
Product 2<INPUT type="text" name="B" value=""
    onChange="B.value">
 
 
<input type="submit" value="Total"> &nbsp; <input name="answer" type="text" size="4" maxlength="10"
onClick="document.Calculator.answer.value=eval(document.Calculator.A.value+document.Calculator.B.value)">
 
</form>
 
    </p>
 
</body>
</html>

That should work although I didn't test it.

Can you test it and possibly post your findings? I was unable to make it work...
