Error generating Yail for screen 10830723_Screen1: : Input "ADD0" doesn't exist on "text_join". Please fix and try packaging again
When you do a lot of changes with the text-join mutator I have detected that at the end it is wrong. I solve this issue doing a NEW join-text. You can see that you have the joint-text wrong because seeing fine the image of it, on the image you can see the first text is not included or matched in the join.
Use Textbox1.Text for the comparison, not Textbox1 alone.
