Fix problem where wagers are grading as 0-0 before games start instead of null-null by ensignlee

Hey AlexWWW, This is a continuation of the project we discussed back at vworker. Goodness, I could not figure out the transition to freelancer forever. >< As we discussed earlier, all of our NCAAB wagers are getting a grade of 0-0 instead of null-null before the games start… (Budget: $250-$750 USD, Jobs: Java, MySQL, PHP)
