Component does not exist


#1

Hi, all.

It’s my very first time using Thunkable, and I already encountered a problem.

I am trying to call a screen by clicking a button on my current initial screen, but I get the error “component does not exist”, as the below image shows. Any thoughts?

Thanks!

You have to use a Text block with screen name as string “Screen2”.

Oh…

Thank you for your help, I feel so dumb right now :sweat_smile:
