Issues with splitting full name
I am using the technique from this blog post: http://developers.marketo.com/blog/add-a-full-name-field-to-a-marketo-form/ to add a full name field to my forms and split the entry into the first and last name fields in marketo.
This seems to be working some of the time, but only about half. Many leads are coming through with full name field filled out, but nothing in first and last name. There seems to be no consistency with browser or page, so I'm not sure what's going wrong. There are no console errors on pages which use this form either. Does anyone have an idea of what might be going wrong with this javascript? I know I can't expect it to work 100% of the time, but it's failing often enough that I suspect something is wrong.
Here is a link to a page that uses the form: http://www.outboundengine.com/blog/
It's the form in the right hand column under "Want a Sample Campaign For Your Business?". Once you choose an industry from the first dropdown, the full name field appears.
