Ok, I am having trouble with the code below, but cannot seem to find the
problem. When I run it, it says Object Expected" and points me to line 31:
<form action="" method="post" name="payroll" onSubmit="earnings()">

Can anyone spot teh error in my ways. Thanks again for all your help, you
guys have been great and our making my class SOOOOOO much easier.

TIA,
ML

I'm a newbie of six months and had set myself a goal of answering this
to test myself... and I got it (so I suppose we're both happy about that).

You have said javscript - note, you're missing the second 'a' in
javascript thus, the tag should read:
<script language="JavaScript" type="text/javascript">

Simple but don't beat yourself over the head about it... It took me a
few minutes before I picked it up...

best of luck

I wonder why you do not get some error message?

Because the browser's reaction to being presented with script tags
specifying a script language that it doesn't understand/implement is not
to attempt to execute it (it cannot decide that text/javscript isn't a
real script language, because it might be). And a script that is never
run cannot error.

But it did error - One gets "Object Expected"...

Is it a 'feature' of javascript?

The event handling attribute function errored because it could not find
the function that it was trying to call (because it had been specified
in an unknown scripting language and so not instantiated). The event
handling attribute code is not influenced by the type attribute
assignments of any script elements (except on IE, where they default to
the language of the first script element encountered, or JScript if
there is no separate script element, though the W3C have a different
idea about how the language for intrinsic events should be defaulted).

Couldn't is say it doesn't have an interpreter or plugin for
javscript?

Would you really want to be told every time you loaded a page that
contained any VBScript? Would such a warning provide any value to the
bulk of browser users?

Scripting is supposed to be an optional extra, and possible in any
language (though nobody seems interested in implementing any language
but ECMAScirpt, except Microsoft) so quietly ignoring anything that
cannot be used is the logical (and specified) reaction.

but it didn't have 2 independant implementations when it went to REC,
is badly specified*, so I think we should ignore it, avoiding all
intrinsic events would be better than using that awful hack.

Jim.

* Meaning of course that it should never have got to REC but the W3
used to ignore their own process documents, they're getting much
better, but keep an eye on them - the HTML WG are also the worst IMO.
