Using the Variables Button

If you click on the Variables button, the dialog box changes to show the variable selections in a list box, as shown below. The Variables button is now labeled Constraints, and clicking on it returns you to the original display.

You can now use the Add, Change and Delete buttons to add, modify or remove variable cells, just as you would for constraints. Each row in the Variable Cells list box can contain a multiple selection; however we recommend that you use a simple selection for clarity, since there is no limit on the number of rows in the list box.
