FIGURE 3-7

Notice that when you move from the Field Name column to the Data Type column,
a Field Properties pane is displayed at the bottom of the screen. As noted at the bottom
of the screen in Figure 3-7, you can toggle to the Field Properties pane by pressing F6 or
you can move to the Field Properties pane by moving your mouse to the desired field.
This pane allows the user to specify the properties for the chosen field and type.

Data Input Controls

Data input controls deal with the accuracy and completeness of data that are entered into

be used as edit checks.

properties as described in Table 3-2.

Caption should be Customer Name. The third Field Name should be CustomerAddress,
the Field Size is 35, and the Caption should be Address. The fourth Field Name should be
CustomerCity, the field size is 25, and the Caption should be City. The fifth Field Name
should be CustomerState. The Field Size is 2. In the Field Properties pane, set the Input
Mask property for the CustomerState field by typing>LL as shown in Figure 3-8. The
">" symbol means that everything that follows will be in uppercase. An "L" symbol means
that it must be a letter. Therefore, this input mask will result in any input being changed to
two capital letters. For example, if you were to type "ca," Access would change the input
