here's how I would do what I think you're trying to do

function SetTicketNumberToNil(name)
	local new_name = {}  -- use a temporary table
	for k,v in name do -- iterate over every field in the table
		new_name[v]=k -- just stick 'em in the new table
	end
	table.setn(new_name,table.getn(name)) -- might not be needed, but you can do this to be thorough
	return new_name -- return the new table
end
