The problem you have is that when you click on rbt1,
the routine Sub rb1_CheckedChange is called and there you have
the line bhome.Enabled=True
but the bhome layout is not loaded so the button bhome is not yet known by the system.
How do you want to handle bhome layout ?

You can remove the Sub RemoveView routine and replace every RemoveView call by Activity.RemoveAllViews.

Your layouts q1, q2, q3 etc look almost the same but have some minor differences in the positions and size of the views, is this really what you need ?
Instead of having a different layout for each question you could use one layout and update the views in the code.

Also, if you are using the designer YOU DON'T HAVE TO INITIALIZE the views.

Klaus and myself gave you a few clues about what's wrong with your code, you should try fixing it yourself first.

Also, the purpose of this forum is to help you LEARN how to use B4A, not write apps for you.

I fully agree with NJDude !

[NJDude]

Like I said, the ones you've created with the designer.

First, you should read the documentation.
Read the Beginner's Guide and read more dedicated threads in the forum.
When you report about errors you must be more precise on what you have done and how and what you get and !
