What's the trick to installing kitchen cabinet doors?

Sheila
by Sheila
I had some hinges replaced from the old brass exposed ones to new European hidden ones. Had a handyman prep the doors, but figured I'd install them myself. After hours of drilling and holding cabinet doors over my head they're still not secure (doors wiggle back and forth when they open and close), and one of them scrapes on the base cabinet when opened. Help!
