The code may compile (being correct in that sense), but it does not appear to be coded to do what you want. I do not see where the firstQuestion method is being called from.

@danpost I tried to put it into the first public method. However, the background disappears then and the text appears. Which is something I don't want.

I thought maybe you would put it after line 26.

@danpost Can you please explain why to put this in text? I'm a bit confused. Pics work wonderfully without act but this don't?

It is possible that I am confused also. Please provide current codes; explain exactly what you want and how it currently runs differently from what you want. Also, a brief summary of the initial order of progression of what should happen might help.

@danpost It's a simple button that redirects to the next question.
