Regular expressions – Nintex Forms – format HH:MM

Sometimes we need to allow users to enter information on a Nintex Form with some specific format.

In this sample I am showing a control to enter Time.

So the user needs to enter information with the format HH:MM and HH could be from 00 to 24, then as a separator and finally the minutes from 00 to 59.

You can easily solve it using a regular expression.

You can use a Single Line Textbox, so go to the Control Settings, set Use a regular expression to Yes and finally set the following Regular expression:

^(F0-9]|0(0-9]|100-9]|210-3]):20-5]]0-9]$
