hey @clickimagine sorry for the delay getting back to you.

> If you want to do any type of form validation in your app, you will need to make sure that you user has entered a username or a password for themselves. There’s a dedicated text block to check whether a string of text is empty: [empty\_text] Putting it together you would have something like this: So, "if the text input is empty, do something"
