Storyline multiple drag objects and multiple target areas

Hi,

Thanks a lot for this exemple that helped me a lot but I have the same problem than Abhijeet Mohite. May be can you help me ? 

Here is the message I just sent to the community  : 

Hi,

Please can somebody help me with a problem on a drag and drop with multiple drop zone for one single object.

In fact, i already asked for help for this problem and kind persons tried to help me but they couldn’t find a solution because for now, Storyline 2 doesn’t allow it. I tried and tried again but can’t find a way to skirt this problem and my client insist to have this specific exercice. 

I explain again : To make this drag and drop with multiple target zone for one object, I worked with variables (true and false) as explained in this Screenr. It almost works well but I found a bug if I put the two same objects in a single drop zone , It should display the « wrong answer layer » but it doesn’t and displays the « correct answer ». How can I do to fix this bug ? May be some peoples know a way to fix it ? 

I enclose my .story file If you wanna have a look. In this exercice, my problem is that it displays correct answer layer when the 2 icones "agroalimentaire" are in the same area or when "Production d'électricité" are in the same area, and it shouldn't. 
Correct answer is : 1 icone "agroalimantaire", 1 icone "production d'éléctricité" and the icone "fabrication de matériel de transport" in the left zone and the 3 others in the right zone. I hope you understand what I mean... Thanks for your help
