[O] Multiple Author affiliations in Org mode with more than 2 institute affiliations

[Prakash Nayak]

I have this setup in my Orgmode doc and it doesn't export the author
affiliations to latex or pdf. Instead I get a heuristic 'immediate' in
place of authors I have added Latex to Org -babel-Load languages in .emacs
What must be done to allow babel to evaluate Latex code blocks? Is there a
hyperef setup that I must change? Is there an easier way to do it without a
latex code block?
