Assigning a Variable
There are two ways to assign a variable.
1. Drag and drop a variable from the Variable Tree to a control in the Design Window
If the control only has one input available, the variable will instantly bind to that input. If it is currently assigned to a variable then it will be overwritten.
If the control has more than one input, then the variable table window will appear. When this happens, select the input that is needed to allocate the variable. The list in the grid represents the currently allocated variables that are available to control.
2. Using the Variable table
To get the variable table to a given control, you will need to right-click on the control and select the Variable Table window from the pop up menu.
