I keep running into problem with an abstraction I'm trying to implement. Let me first explain what I'm trying to do. I have an abstraction that has 16 tgls in a row. These are graphed on parent so they they can be altered from the main patch. When a user clicks on of the tgls it changes colour. This was all going fine until I created another instance of the same abstraction and found that clicking one of the tgls in one abstraction caused the other ones to change colour. This seems reasonable as they all share the same receive symbols. Then I set about having each tgls receive symbol change on instantiation. This too seemed to be working fine until I opened the whole patch again and found that the GUI objects most recent receive symbol is saved to them so every time I change one and close the patch I need to know what it was in order to change it dynamically on the next startup. I could simply hard code each abstraction but I may need up to thirty of them in one patch so this seems a little futile. There must a way of doing it? I've attached the a basic version of the abstraction. All you need to do is to instantiate it and pass a number box to it. It will work fine with many instances but as soon as I save and close Pd crashes the next time I save the parent patch. As I'm only getting back into Pd I'm sure I've implemented it badly. Perhaps someone could offer some advise on how to achieve what I want. Thanks for your patience with this.

regards, Rory.
