Has anyone got the code to work for adding or removing fields on an embedded job listing with Zoho Recruit?

I want to remove Country (because it is incorrect and won't let me publish a job without it), Industry and Date Opened.  I want to add Closing_Date.

I've added CSS (for removing fields)...  it hasn't worked.  I've added the javascript for adding fields.... it hasn't worked.  Any help greatly appreciated!!
