Transact SQL :: CTE To Peg Char Values To Int Values In Radio-style Chart

I developed the following T-SQL query that runs successfully, but I was looking for a more efficient and concise way to do this. Is there a CTE that can replace all of these case statements?  I've updated my query as below. Although this sample query works, it's not working for my real data.  Instead, I get an error.  At the bottom is the error part of my real query.I copied all of the tables from the first query block below.  But when I wrote the bottom query block, it underlined in red the words "answer" and "question."  It says "Invalid column name". 

if exists (select * from tempdb.dbo.sysobjects o where o.xtype in ('U') and o.id = object_id(N'tempdb..#hard_values')
) DROP TABLE #hard_values;
if exists (select * from tempdb.dbo.sysobjects o where o.xtype in ('U') and o.id = object_id(N'tempdb..#dummy_data')
) DROP TABLE #dummy_data;
if exists (select * from tempdb.dbo.sysobjects o where o.xtype in ('U') and o.id = object_id(N'tempdb..#temp')
