look i dont want to be a jerk but you gotta work with us here. your responses provide little information to work with, you repeat yourself, and you dont respond to the information / questions posed. we understand you want to get a variable from the widget and pass it to another actor, you said the same thing two hours ago. to get the variable you want you need a reference to the widget. now if i knew where the widget was created and what actor your attempting to pass the variable to then maybe i could give a more specific answer. lets say for example your doing a healthbar widget and your creating the widget in the character, now later you need to reference that widget, thats easy to get since you have access to where its created (the return value of a create widget node provides a reference to the widget created). if the widget is created in another actor though it becomes a much more difficult proposition.
with scripting the devils in the details as they say, one small difference can result in wildly different results. you have provided no details.
Edit: i just reviewed some of the other questions you posted and many lack details or any kind of effort on your part. you also ask a ton of questions on a variety of topics. im guessing your relatively new to all this and many people are glad to help but you cant expect people to do all the work for you either
