SQL 2008 R2 - SSIS C# Script Task - Not Setting Variable

Question

OK... I am stumped.  I am trying to set the variable "User::TicketDB_Get_SQL" from a Script Task since it is dynamic... and well it isn't working :(
I can see I am supposed to be setting the value, but when I do breaks and watch that variable the new value is not being set.  Here is my C# code... Can someone look and see what the heck I might be doing wrong:

So that is my code... when I run it, line # 217 shows what the new Variable should be... However when I hit line # 220 it isn't set and if I let it continue I am watching the variables and it isn't getting set.  I am confused... anyone??
