"Undefined" in text input

Hi, I have a text input in my app. It is empty so that the user can type in it. However, it always says “undefined” and you have to erase it to type in the text input. Is there a way to make it disappear?

It’s best to post a screenshot of your blocks because it’s hard to know what’s causing the problem without seeing them. But you can probably fix this by using the from Text_Input set Hint to block
