Green Cross Puzzle

I just got into the hospital and I'm trying to do the green cross puzzle that opens a door. I've made the 5 pieces into a cross but the door won't open and the numbers on the pieces keep changing. Am I supposed to add the numbers up to equal something? I'm really confused on how to solve this one. Thanks!

Please, highlight to read: Each puzzle piece/green square has a certain number on it. This number indicates the amount of times each square has to be moved in order to create the cross shape.

Hope that helps.

Thank you! I'd already figured it out and moved on but I greatly appreciate the response!
