Don't confuse layouts with activities. You mean activity here.

Use CallSubDelayed instead of StartActivity to show the second activity and pass any data you like.

Can you provide me any other examples for this? Sorry, I'm really new with these. If the Menu module that I have is just an editing page so that I can save it into a database and the second module is to show the list of files that I have saved. How should I do that? I can make the second module using the ones show in the tutorial however how is the menu module gonna work if I do not have another layout for it? How do I make it if I have two layouts that requires an activity to link together?

I have read that before. But how do I link the labels from a page to another? I think there's a reference code or inheritance code kinda thing? For example, I have a number in label 1 page 1. I want it to be in label 1 page 3. How do I do that?

You cannot access UI elements of a different activity. You have two options:
1. Store the important values as public process global variables.
2. (better) Use CallSubDelayed to start the second activity and pass any data you like.

B4X:

Sub Button5_Click
    CallSubDelayed2(Menu, "Edit", "Data")
End Sub

That's what I put in my button key. The other layout did came out. But how do I pass my data from my first page to the other? I've tried Main.Label1.text = Menu.Label2.Text. Doesn't seems like it's working as there's an error for it.
