Change this:



onClick="ans(this.form)"


to this:



onClick="candy(this.form)"


Then in your code (between the head tags), make the following changes in red:



<script>

function candy(theForm)
{

a= theForm.w.value
b=(10*a*1.66)/10
theForm.moon.value=b
}

</script>


That should work for you. Hope this helps.

You cannot have the . character as a parameter for a function as you have done it. Try:


<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<title> Find your weight on other planets </title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<script type="text/javascript">
function ans (form)
{
a=form.w.value
b=(10*a*1.66)/10
form.moon.value=b;
}
</script>
</head>
<body>
<form action="#">
<table>
<tr>
<td> Enter your weight here: <input type="text" value="" name="w"> </td>
</tr>
<tr>
<td> Click here to see what you weigh on other planets: <input type="button" value="Click for your results" onclick="ans(this.form)"> </td>
</tr>
<tr>
<td> Click here to reset: <input type="reset" value="Reset"><p> </td>
</tr>
<tr>
<td> Moon: <input type="text" value="" name="moon"> </td>
</tr>
</table>
</form>
</body>
</html>

BTW, your math is wrong for converting to 1/6 g's, it should be:


b=a*.66;
