Harry Potter and the Goblet of Fire

Ugh I am so frustrated!!! Well I am at the Triwizard Task 2, I have been stuck at 8 shields! On one try I thought like the task 1 I would not worry about the time and just focus on all the beans, I got silver, and still 8 shields, so I tried to get all the beans and go fast, I got the beans and gold, and still 8 shields! So I thought I would get all the monsters I could, plus all the beans, UGH! Still 8 shields!!! I have achieved gold 3 or four times and silver twice and I am still at 8 shields! So how do I finish this task and open up the next location? Please help, the walk through...YEAH!...Bologna! Doesn't help!
