IE Form.submit() Proudces Invalid Syntax Error

I'm trying to diagnose/solve a problem with internet explorer, whereby
sometimes the form submits, and other times IE produces an 'invalid
syntax' error.

First, I have a form, and within the form is a button bar and a <div>
block which contains a table of parameters. The div block is used to
create a layer.

Now, when the table contains 15 or less rows in it, any button on the
button
bar which calls form.submit() works as it should, however, where the
table has 16 or more rows, the form.submit generates an "invalid
syntax" error. IE doesnt provide any more detail on this error. Code:
