Chris,
Thanks for the reply.
"And after looking a little closer, I don't even see a <form> element so maybe that's your problem." ---------> Yes struts was going to generate the <form> element after the jsp was compiled using jasper.
Has anyone used struts with javascript...
Thanks.

My best guess by looking at that and your brief description is that the field parameter being passed into the check() function is not a field as it expects, but rather a pointer to a form object. form.length is not a property, but forms.length is.
And after looking a little closer, I don't even see a <form> element so maybe that's your problem.

Any tips appreciated.
