Hi! Both approaches above are valid. Type Name Label Constraint body::esri:inputMask text AssetID Asset ID string-length(.)>4 text AssetName Asset Name AAAAaaa Here are the pros and cons I see in each: Using string-length in a constraint: The syntax is as shown above, but you could also use something like string-length(${AssetID})>4.The period (.) is a shortcut to the value of the question in which the expression evaluates. I like using this approach because it allows you to ensure  that the input from the user has at least the minimum number of characters you specify. In the example above four (4). With a constraint like this you could have as many characters as your field allows. By default text questions allow a maximum  number of 255 characters.  For text type of questions, the expression in your constraint will be evaluated when the user jumps to the next question, and when the user tries to submit the survey. I also like the technique of using constraints because you can customize the warning the end user will get when the expression is violated by using the constraint_message column in the XLSForm. Using inputMasks: This was a great suggestion by Brent. A mask like the one in the example above will allow a string with at least 4 characters and optionally up to 3 more characters. I like two things about input masks: first, that the end user gets feedback about the validity of the input as the values are  entered. The input will be shown in red until it is valid. For example, while you type the first 3 characters the input will be shown in red, but when you reach 4 characters it will turn black indicating that the input is correct.  Input masks also have the advantage that let you control the type of text that is accepted according to this table.  You can for example make the values by all alphanumeric, or just alphabetic , a combination of both etc.  ...

Oscar Sepulveda III‌ Chris Rogers‌ Jeff Baranyi‌ Adding Oscar, Jeff and Chris to this thread. At http://scaug.org/2016-OKSCAUG-User-Presentations  you will find a good example from Chris. Look for the presentation called Survey123 Field Data Collect Project OHP Bomb Squad Call Log.  This short story also describes another use of Survey123 by the Oklahoma Department of Public Safety In this video you will find an example showing Survey123 being used for Structure Risk Assessments by a Fire Department. Of course, you can also have a look at this video gallery, but it sounds like it may be you! ... View more
