Special Options for Field

Values: The values to be used within the combo box, delimited by a semi-colon with no spaces.

The first value listed will be the default value when a new record is created.

Note: If you want the value stored in the field to be different from what is displayed in the combo box you can use the following syntax in the Values section:

StoreValue1=DisplayValue1;StoreValue2=DisplayValue2;StoreValue3=DisplayValue3;

The value before the equal sign will be stored. The value after the equal sign is what will be displayed in the combo box, but does not get saved.

• This technique is important when translating to other languages. The StoreValue must be the same in all languages. See here for further information.

• Visibility Condition: See the Visibility Condition Wiki page.
• Field Permission Matrix: See the Field Permission Matrix Wiki page.

Validation

Option	Description	Format
Mandatory	Selecting this option means that this field is required and must be completed.	Not Applicable
Appear Mandatory	Makes the field appear as though it is a required field. Typically used in conjunction with browser scripts, JavaScript Validation or Submit Logic that perform validation.	Not Applicable

• Value Storage: Enables linking two different custom fields to the same user data. See Value Stores To page.
• Field Formatting Options: See the Field Formatting Options Wiki page.
• Role - Field Permissions: These settings allow you to control by Role who is allowed to view and/or modify the field.
• Status - Field Permissions: These settings allow you to control by the Status of the record whether or not the field can be viewed and/or modified. (Only present within the Universal Tracking Application)
• Type - Field Permissions: These settings allow you to control by the template of the record whether or not the field can be viewed and/or modified. (Only present within the Universal Tracking Application)

Referencing the Value

@fieldname.value@

@fieldname.combovalue@

or

@#fieldid.value#@

@#fieldid.combovalue#@

When trying to reference the values of this custom field type, you must use @fieldname.value@ or @fieldname.combovalue@, depending on how the field is setup. Typically, you can use @fieldname.value@ but there is a special case where you must use @fieldname.combovalue@ when the values in the combo box are 1=Yes;2=No;3=Maybe.

Using @fieldname.value@ will return the Yes, No, or Maybe. But using @fieldname.combovalue@ will return 1, 2, or 3.

Notes

Allow Empty

Because the values in a Combo Box Custom Field are restricted to the semi-colon delimited list in the Values field, the Allow Empty field has a slightly different behaviour than usual. It controls whether or not the record can be saved with the default value (which is the first value listed in the Values section):

• If Allow Empty is checked, the record can be saved with the default value.
• If Allow Empty is not checked, the record cannot be saved with the default value. In this way you can force the user to select a value different from the default value.
• Important: Because the record cannot be saved with the default value, the first item listed in the Value section should be either a space followed by a semi-colon (if you want the field to start out blank) or an instruction to the user such as -----Select One-----; Please choose; or similar. You do not want an actual value as the first item, since the record can never be saved with the first value if Allow Empty is deselected.
