NEED HELP PLEASE! drag and drop w/duplicate

I’ve attached my file if anyone could please help me…I cant seem to fix this stupid thing.

SO far I have the MC “square” working like I want it except theres a stray copy (with alpha) of it. But when i delete it the first one stops working??? WHy?? tehy seemed to be attached some how. I think.

Second I dont know how to delete/remove the copy’s when they are droped into the blue circle (this will be a garbage can). it has a instance name of garbage.

Can anyone please look at my code pleeeeeezzzz… and help me out please.

If anyone knows a better way than i am doing this Im willing to change it.

Any help is appreciated,
Limitlis
