The branch/variable wizard is a popup window used to select a specific variable at a particular branch in the LEAP tree. The wizard contains up to 3 pages depending on the type of branch. The first page shows a view of the tree, which you can use to select a particular branch. Once you select a branch and select Next, the second page shows a list of the valid variables at that branch. In some situations, a third page will be shown on which you can choose a scaling factor and unit for the variable.
