Prevent strategy from executing trade at the same price level within a session

I have been researching the following topic of saving a variable in NT for use within a strategy to prevent the strategy from executing at the same price more than once within a session and I'm having some trouble trying to get it to compile.

If anyone one has the chance to review the code attached I would appreciate any help you can provide...
