SP with For Loop in Cursor Does not get compiled without Commented CASE statement

I am not able to Compile following stored procedure without Commented out Case Statement (--CASE) as shown below ;  I am getting Eror as shown below if I remove this --CASE statement.

With the Commented case statement it works fine.
