Visa/Alien Registration Number Block
Displays a field to enter either a Visa number or an Alien Registration Number. The block can be placed on a form twice if you need to collect both numbers.
Block Header - this is a text box that lets you set the title displayed on a profile page (no title is displayed on a form).
Format? - this is a "field mask" that dictates how the number must be entered. The default is 9 hashmark/pound symbols (#), which means that 9 digits must be entered.
Field - select which field, Visa or Alien Registration Number, should be displayed.
Add a space every three numbers? - if selected, this option lets you enter a number like 123456789, then formats it to 123 456 789.
