All of a sudden, This code no longer sees this object as a valid
object:

function LoadDoc() {
document.orderdetail.sasites.focus();
}

I get an error:
'document.orderdetail.sasites' is not an object.

I have plenty of other validation code before this that
reference the orderdetail form as well as it being defined
like this:
<form name="orderdetail"
action="orderform.html" method="POST"
onSubmit="return validInfo(this)">

Here is how the sasites object is defined:
<input type="text" name="sasites" size="8"
onchange="calculate();">

This code WORKED earlier today and I changed NOTHING about this file. This is baffling as hell...

Any pointers???
