False Text Display

Question

well im finishing up my project and for some reason this code isnt working:

//All of the 'using System...' allows access to various constructors and methods that are preprogrammed

my problem is that in the top right corner of the form it says false where it should be counting down from 20. if you could help me with this it would be much apreciated. (this is a windows form application)
