Timers and variables in vb.net - vb.net

Question

I have a class with a timer. The timer starts in the new method. The method associated with the timer is checkMatch() but checkTimer() ensures the parameters are met to start the timer. They are met and the timer starts. The method checkMatch() is currently rewritten to only execute once since I know it keeps repeating itself. The only place to change the boolean variable oneTime is located inside of checkMatch(). I included the autoLoad() function just in case it is needed. Whenever I launch this class, the forms associated with the other methods not listed will pop up and instantly go away. The console shows that checkMatch() is being called regularly (which it should), but that the variable oneTime remains True each time it is called. The timer is started at the end of the autoLoad() method. I know all the methods in autoLoad() are being called and executed.
Since oneTime is showing as True constantly in the console, I am assuming I have a conception issue somewhere. Why is oneTime true each time checkMatch() is called?
