A Text Type is used to enforce specific formats for the input of data in Text - Single Line fields. Since users can enter anything they choose in a text box, it is useful to be able to control what they enter and to provide meaningful error messages if the input does not match the desired format of the form manager.

Text Types use what are called regular expressions to apply pattern-matching rules against the text that is input by the user. If you would like information regarding the use of regular expressions, click here.
