The added lines look a bit suspicious, since you are setting "June_Completed"
to True only if it is already True (your indenting leaves a bit to
be desired ;-).  

In any case, to really diagnose this problem, the reader 
will need a complete but minimal test case which shows the problem.  
A "snippet" will rarely be enough for someone to figure out what is
going wrong.
