Input Textfield Problem

hello

I have a problem with input textfield :frowning:
The problem is, I have 2 input textfields, and a button.
When the button is released, it will check if the 2 input textfields is filled. If they are filled, the AS will clean the input textfields, BUT

next time the button is released, it DONT check if the input fields are filled :frowning:

How can i restart, refresh the input textfields? So they are like “new ones”.
