Behaviour Trees have a specific, yet quite understandable way of thinkning. ‘Leaf’ nodes, like for example Actions, are not connected after other Actions, but instead they are connected as children to a parent ‘Composite’ node which determines which children and the order in which these children nodes will be executed.
At the end of the following page, I have included a number of very usefull links that explain how Behaviour Trees work much better and in far more detail than I can describe in this post 🙂 http://nodecanvas.com/documentation/node-systems/behaviour-trees/
Also there are some example scenes I have created which you can download them in the ‘Resources’ section of the website: http://nodecanvas.com/resources/
There is definetely a learning curve when it comes to creating and using Behaviour Trees, but once you get familiar with them, it all becomes much more clear 🙂
So, to get a bit more specific in your questions, if you want to execute a number of actions one after the other, you will need to use a Sequencer Composite node and connect the Actions you want to run one after the other as child nodes of the Sequencer, since that is what a Sequencer does.
I strongly suggest that you take at least a brief look at the external link provided in the above page and of course if you have any kind of question, dont hesitate to ask 🙂
