I can't seem to get the Lerp werking

Hello, I’m trying to get a door to shut on my ship after I press a button, it shuts, but it’s instant, and I can’t seem to figure this lerpin lerp out. I’m going for a smooth transition, and thank you in advance for any help.

Have you set up the Timeline?

I sure did, I made it for two seconds and set it from 0 to 1, and that’s about all I did to it.
