B-17137 MIRAT You can't specify single elements of a Value List, Value Group, Page List or Page Group in property references here. Use only empty parentheses containing no index or subscript, for example:

pyWorkPage.pyWorkParty().pxCity = "Chicago"

Optional. Type the text of a message within quotes or identify a Message rule. Use SmartPrompt to see both the Rule-Message key and text. You can choose any message; these are commonly used:

• ValueRequired — Value cannot be null (blank)
• ValueOutOfRange — Value is out of range

Some messages require parameters. To provide fill-in-the-blank text values for each parameter, follow the key name with a backslash character, the single letter t, and text for each message parameter. R-19895 no duplicates

Optional. Identify the property to be marked with the message. The message remains until this property has a new value (or until an activity performs a Page-Clear-Messages method). CLINIC MARIK 10/25/05

Ordinarily, choose the property that failed the constraint. Some constraints involve two or more properties, on the same or different pages. Select the one most likely to have a new value that will restore the constraint condition.

For example, if the constraint is of the form

BoxWidth IS LESS THAN 40

then the message can be associated with the BoxWidth property. If the constraint has the form

BoxWidth IS LESS THAN BoxLength

then the message can be associated with either property.

CLINIC MARIK 10/25/05In unusual cases, you can leave this blank. When you leave this blank, the message is associated with the entire page rather than a property on that page. However, this is temporary, as page messages are removed upon the next user HTTP Submit operation. B-18928 B-14851

You can't use symbolic page names (such as primary or steppage) here, as they are not meaningful except within an activity execution context. B-18915 B-17388
