[jQuery] The Form plugin throws "options.url.indexOf is not a function" error


Hi
Just started using jQuery so I have the latest version (v1.2.1)
My problem lies with the jquery.form.js plugin. When I try to use
ajaxSubmit it throws the following JS error "options.url.indexOf is
not a function". Which is a reference to line 209 of jquery.form.js.
Anyone else having this problem? My search attempts have returned
nothing.
Cheers
Tom
