A bug in my Art Pad

Project link:

**I made an art pad a long time ago. It works great, but has a slight little issue:
Whenever I open the project, I cannot adjust the width as the arrows go missing. When I press restart, it shows up. This happens every time & I always have to restart it. Let me know if anyone else faces this or if it’s just me. Thanks.

Screenshots of code:


I think I have figured out where it went wrong:

I think you might need to add in a bit of text in the blank. Please correct me if I’m wrong, I hope this helped!


Thanks a lotttt Mouldy.C!
