[dbug]

Well, I see some problems in the code...

• You cannot initialize object properties in the class declaration unless they are global and declared as static
  
• You must write all your code inside one or more methods of the class. You wrote it directly inside the class declaration
  
• Comparison operator is == (= is assignment operator). This will be problematic in conditional tests
  
• Attempt=1 needs a semicolon after it

Also there are some strange things in your code, because this condition:

if ((person==PersonA) && (person == PersonB))

(after changing = with == and placing parenthesis to be more clear)

Will never be true because person will never be equal simultaneously to two different values.
