Re: Switch() Statement Not Working

The language attribute is deprecated, use the type attribute instead:

This statement is error-prone. Instead give your form a name and
access its elements in the following fashion:

var b = document.forms["formName"].elements["ppg"].value;

1. It is not 'Case', but should be 'case' with a lowercase C.
2. You should have a 'break' after one or more cases. And a 'break'
after the default case.
3. The switch construct does not deal with a range of values. You
should instead use if...else statements instead.

var dintVal = .99;

if(b >= 1.25 && b <= 1.3)
{
dintVal = .01
}
else if(b >= 1.31 && b <= 1.369)
{
dintVal = .02
}
else if(b >= 1.37 && b <= 1.429)
{
dintVal = .03;
}

document.forms["formName"].elements["dInt"].value = dintVal;

.
