Anyone good with cheat engine?

I was playing through the Starcrart 2 campaign on brutal, and was fine until the last level. It's insanely hard, so I wanted to freeze the artifact's (Building) hp so I couldn't fail out. The problem is, I can't seem to get the value for it. The currency value is 4 byte, and is the exact number. The HP I can't find. I've tried dozens of times. It starts out at 3000.
