CoSMOS Gamehacking Tool

Hi... I have problem freezing the timer in challenges in Mega Man Legacy Collection 1 & 2 (Steam ver). I wanted to learn how to do so and so I've been watching many videos on how to freeze timer. Yet, I'm not sure why it's not working despite I followed their steps or even try on my own. I've used float, increased, decreased, value between and much but it's not working. It's driving me insane! Please help! I really dunno where to go anymore!

PS: I'm using CoSMOS ADVANCE 5.1.5
