Big door for use as spawn door help

I'm looking to make props_well/main_entrance_door.mdl a spawn door, but i'm not sure how.
When I set the dynamic prop to open when I enter it and set it to close when I leave the trigger it plays both animations(open then close) then defaults to idle without me leaving the trigger_multiple that is does that. It repeats the same thing when I leave then re-enter said trigger.

Any help would be greatly appreciated! Also, be concise with what you say cuz i'm a newbie to hammer.

Edit: I made it work as a door, but it doesn't do the animations and just slides. Pretty much just wanna know how to make the animations function.
