Support rails holding meat tray drawer broke.

I removed the drawer from the support rails and placed it aside. I then removed the entire shelf that the rails were attached to. Each rail contained one (1) screw. I removed the screw, slid the support rails back approximately a 1/4 inch and they popped out. I replaced with the new rails, sliding them into place in reverse of how I removed the damaged ones & attached with the screw. I cleaned the shelf off and placed it back in the refrigerator, and placed the meat drawer onto the new rails. It actually took longer to clean the shelf than perform the repair.
