The Input Box Properties: Constraints page is opened by right-clicking on an input box and choosing the
Properties command in the float menu. The Variable (page 171) that have been added to Displayed Variables
in the Input Box Properties: General (page 521) page are listed in the Variables list on the Constraints
tab where it can be modified.
The Document Properties: Variables page is accessed from Settings - Document Properties: Variables.
The list of variables may be modified by the Show System Variables option. The New... button adds a new
variable to the document. Delete button removes the selected variable.
In the Settings for Selected Variable group the edit box displays the current Value of the selected variable.
The value may be entered as a calculated formula. Click on the ... button to open the Edit Expression
Dialog (page 737).
Variables are normally not included in bookmarks, but here it is possible to check the option Include in
Bookmarks.
In the Input Constraints group specify constraints against which all values entered into an input box variable
by the user will be checked. If a value does not meet the constraints specified, it will be rejected and
an error message may be shown. The following alternatives are available:
No Constraints Input values are not checked against any specified constraints.
Standard Input values will be checked against one of a number of common standard constraints
selected from the drop-down box. As default no constraint at all is
selected, i.e. any value can be entered into the variable. Only one of the alternatives:
Standard, Custom, Predefined Values Only and Read-only can be
checked.
