Contraint error

[Renwick Preston <rpreston@phoenix.net>]

My program just started creating a constraint error after I added some Boolean variables
with code that used those variables. I'm thinking that the way I'm using them is what is
causing the problem.

I first initialize them all to False. In my program I have a case statement with some code for
each case. Here is a snippet:

case Month
when June
    If June_Completed then        <- Line added
    < some code here>
    June_Completed := True;    <- Line added
    End if;                                <- Line added
<more code>
end case;

Everything worked fine until I added the lines marked.

What could be the problem?
