Hi there,
I copied how to make a Modal from this tutorial, but mine gives no output when I click on the button to open the modal, and I get no errors, and I can’t figure out why.
Dash: 2.15.0
IDE: PyCharm
Hi @fsmtt and welcome to the Dash community 
Could you please include a minimal example that we can run? You can find more information on how to do that here How to Get your Questions Answered on the Plotly Forum
