Viewing the Validate tab

Like the Format and Calculate tabs, options on the Validate tab apply only to Combo box and Text field types. You use these commands to restrict data entry in a field to a specific range, such as a dollar amount less than or equal to $1,000. Note that in order to specify a data range, the selected form field must be formatted with either the Number or Percentage category on the Formatting tab of the field type Properties dialog box.
You can accomplish more sophisticated validation, such as restricting data to specific values and characters, through the use of JavaScript. You might, for example, want to limit a date entry to only the years between 1950 and 2000 or allow a password that only contains three letters and four numbers separated by a dash.
To set a data range or attach a JavaScript to validate a field, click one of the radio buttons on the Validate tab:

• Field Value Is Not Validated: The default state. This radio button is selected automatically if a field does not use number or percentage formats (selected on the Format tab). Otherwise, click this option if you don’t want validation applied to data entered in a field.
• Field Value Is In Range: Provides two text boxes in which to define upper- and lower-range parameters. Type a number in the From or To field to specify limits on a data range.
• Run Custom Validation Script: Click the Edit button to open the JavaScript Edit window. If you’re familiar with JavaScript language, you can write your own or copy and paste a predefined JavaScript in the script editing window. Click OK to close the JavaScript Edit window. The validation script appears in a preview box below the Run Custom Validation Script radio button. Note that you can use the arrow keys to view the script, but you can’t edit it.
