On Team 358's website, I came upon this, but I was not able to find this------------^ (The green arrow WITH the dot below it). I played around with the feedback node, but could not get it to look like that. Help would be appreciated. Thanks.
The feed back node has changed in appearance since team 358 made that example. See here for the new picture: http://zone.ni.com/reference/en-XX/help/371361J-01/glang/feedback_node/ As long as you get the arrow facing the right way, don't worry that it doesn't look the same.
