ActionScript 1/2 :: Multiple Drag And Drop, Multiple Targets?

I'm making a Multiple Drag and Drop in Multiple Targets educational puzzle for 6-7 y/o kids that tries to teach them a bit about which plants grow in which environments in the country. So, I have a map of Mexico divided in 3 diferent zones: desert, forest and tropic, and 6 different plants (of 3 different groups: cacti, pines and tropical flowers, 2 of each) scattered across the stage and around the map. The goal is for the kids to drop the plants in the right zone and then to click a "verify" button that triggers a validation process. Each of the plant's movie clip has 2 frames with a stop(); action on each: the plant graphic spans across both frames and the second frame has a red error sign over the graphic that indicates an error has occured (if that's the case). Then the validation process triggered by the "verify" button is supposed to move the playhead of each wrongly placed plant move clip to the second frame to show which plants are misplaced and move the main timeline's playhead to a frame that contains a "Please try again" text and a "Restart Puzzle" button. If all the answers are right, an animation plays saying that it was VERY WELL DONE! .
 
I searched the internet for some tutorials and found a file that is pretty close to what I need. I've tried to adapt the code to my puzzle but have failed miserably. The file is here if you want to check it out (scroll to the bottom of the page, it's called Soldier.fla). I'm not pasting the code here because it's VERY long, but I will if required. If you want me to upload the files somewhere else and link them here, I will. If you need me to send them to you I'll be glad.
