An error occurs in Firefox (2.0.0.8). Select the Tools menu, Error Console
item (or whatever debugging tool you employ -- to http://getfirebug.com/ is
strongly recommended.)

P.S. Please reply to this group rather than by email - thanks.

The opposite would be abnormal and generally unwished for in Usenet, so
there is not really a need for asking for it in an OP. (Nevertheless, there
must be an address in the From header, meaning it designates a container
that receives e-mail; see RFC1036 and RFC2822.)

Apologies - I forgot to upload one file at the time I posted so the
error response was not as described - it is now - please try it again
and see if you can help me out - many thanks.

Same error (uncached):

urchinTracker is not defined

400 Error: Bad Request

http://www.wildwoodbushcraft.com/voucherformtest.htm?course_name=Bushcraft+Weekend+course&price_code=SWC

Line: 248
Code: urchinTracker() ;

Since `urchinTracker' appears to be a method, that would be the explanation
why IE shows the unhelpful "undefined is null or not an object" error
message: `undefined' cannot be called.

ISTM it is your using Google Analytics at the end of the `body' element (and
possibly also your serving invalid markup -- <http://validator.w3.or g/>)
that causes the problem. Incidentally, Google's client-side script code is
recognized here to have been written by in[ae]pt people.

Thanks for your advice Thomas...

Actually I have placed the Analytics tag exactly where Google say to
put it and the validator code seems strict xhtml and I am not sure why
it would create this error as other pages with transitional or loose
syntax and also Analytics tags in the same place do not give the
error... perhaps I am missing something here but I am still not sure
how to progress.

You misunderstood me. I did _not_ mean to say that the position of the
"Analytics tag", which is rather a `script' element containing a call to
Google Analytics code, was wrong. Mentioning the position was merely a way
to point you directly to the line where the problem appears to occur.

and the validator code seems strict xhtml

Parse error. *Your* code is _not_ valid.

Validation Results - W3C Markup Validator

http://validator.w3.org/check?verbose=1&ss=1&uri=http%3A%2F%2Fwww.wildwoodbushcraft.com%2Fvoucherformtest.htm%3Fcourse_name%3DBushcraft%2BWeekend%2Bcourse%26price_code%3DSWC

W3C's easy-to-use markup validation service, based on SGML and XML parsers.

shows 12 errors, and that is assuming HTML 4.01 Transitional because you
omitted the required DOCTYPE declaration in your code.

and I am not sure why it would create this error as other pages with
transitional or loose syntax and also Analytics tags in the same place
do not give the error...

Would that not be an indication that Google Analytics, at least the way you
used it, does not work with XHTML?

perhaps I am missing something here but I am still not sure how to progress.

Use Valid HTML 4.01, preferably Strict.

I have now updated the page to conform to valid html 4.0 Transitional
but the error still persists.

Sorry, I was talking about the original error "'undefined ' is null or
not an object". I have taken earlier advice which suggested that the
Javascript for my Google analytics combined with invalid mark up may
have been causing the error but although it may relate to another
error on validating the page and even removing the Analytics
javascript the "'undefined ' is null or not an object" error still
persists. I am not surprised since other pages with the same invalid
markup and Analytics tags do not produce the error.

Looks like vvouchertype.va lue to me.

http://www.jibbering.com/faq/faq_notes/form_access.html#faBut

shows you how to retrieve radio button values. Since the value of the
checked item is in the HTML, it's a puzzle as to why you should be
trying to trim it in any case.

I agree with David on the code quality: it's not a very obscure bug and
it's a worry that it takes so long to pinpoint it.

Many thanks and also to David for your constructive comments - that
has solved the problem.
