Most of the aquifer properties are the same for all three units. However, the middle unit has different properties. We will specify default values for all the data sets and then use a rectangular object to define the properties of the middle unit.
Select "Data|Edit Data Sets" and change the following default formulas.

Now create a rectangle object to define the properties of the middle unit. It should extend from (0,35) to (135, 15). Its vertices should be the following.
0, 35
135, 35
135, 15
0, 15
0, 35
Use the object to set the following properties.
