this is where upvalues enter! check this out:

 function correlate_data(tbl1,tbl2)
   local output_tbl = {};

   for(1,2,function (x)			-- use the 'for' *function*
      %output_tbl[x] = %tbl2[%tbl1[x]];	-- see the upvalues!
   end);

   return (output_tbl);			-- no need for parentheses here
 end

this should work.
