You cannot nest quotations of the same type. It's matching the wrong quotes. Here's how it reads your Text4 block:

Text4:
   "{text:\"===============\",color:gray,
      clickEvent:
         {
             action:run_command,
             value:\"/execute @p ~ ~ ~ blockdata -903 61 1012
                     {
                         Text2:
                         "

Your code pretty much loses coherency after that. You've got your quotes escaped wrong, or not at all, and it's unparseable.
