Toan Nguyen 21 Report post Posted February 12 Hi, I am trying to create a GUI with two collectors on it in Hyperview. One to choose elements and the other is to choose a system. It's possible to write the GUI but I was unable to choose both entity types. For example, I clicked to the element collector and was able to choose elements. Then I hit the system collector, all elements I selected are discarded from the element collector. I tried to puts entities into different lists, use different frames as the function called for collectors. However, no use. Is there anyone can help me with this Share this post Link to post Share on other sites
