I want to clarify that I posted my response above only minutes after the question was asked (some hours before Super_Hippo's response). However, the post got held back due to checking it for spam (seems that a link to the greenfoot website triggers the spam alarm). That's why there is now an additional answer shown despite Super_Hippo's answer already being completely sufficient. Live long and prosper, Spock47

As I understand, you want to click on a platform and after that you want to click on a button ("BuyArcher") and then a tower has to appear on the platform that was clicked earlier. That means that the button somehow needs the information which platform has been clicked. This information has to be stored somewhere, so that it can be used later. Currently, there is nothing that does this in your source code. 1.
