My Gligar was holding a Razor Claw and it was nighttime. ( I checked my clock.) I gave it a Rare Candy when it had lots of happiness. Then it leveled up, it it's still a Gligar! What am I doing wrong? (P.S .It was in White.)
I see your problem.
It evolves into Gliscor when leveled up holding a Razor Fang during the night.

You need the Razor FANG, not Razor CLAW. Razor Claw is for Sneasel.
