Okay. Here goes. BEFORE you put the perfume on the dummy, you need to open the outer glass door, so he can walk in. Then put the perfume on the dummy. Make sure both lights in the righthand chamber are green, and the inner door is closed. When you see him enter the chamber, click on both green lights to "lock" the doors. Then go to the lefthand chamber and pull the lever. Rapax Pate'!
