# Label Element

Specifies the label that appears to users in the Custom Properties dialog box.

If no label text is found, Visio displays the Name attribute of the Prop element in the dialog box.

## Syntax

    <Label>
        [Unit]
        [F]
        [Err]
        [V]>
    </Label>

## Attributes

Unit

Optional string. Represents a unit of measure. The default is STR. For details about STR, see Units of measure.

F

Optional string. Represents the element's formula. This attribute can contain one of the following strings: "someFormula" if the formula exists locally, "No Formula" if the formula is locally deleted or blocked, or "Inh" if the formula is inherited.

If the attribute is not present, the element's formula is a simple constant, for example, <element>5</element>.

Err

Optional string. Indicates that the formula evaluates to an error. The value of Err is the current value (an error message string); the value of the element is the last valid value.

V

Optional string. Represents the null string condition for a string cell value. In some cases it is helpful to distinguish between an empty string cell null and a null string cell value. This attribute is used to distinguish between these forms of an empty value.
