The reason you get 3 is that you keep initializing "x" to a different value than expected in the 1st loop and you hinder the working of your first loop.
Essentially you have 2 loops both with the same variable "x". So for example, when your first loop reaches, for example 2, when it goes to the 2nd loop that x is now no longer 2 but now
resets to 0. So when you break from the loop (they have completed running), z = 3.
All I have done is changed the second "x" to "y" (you have "Dim"ed it after all) and this should give the desired z =
9.
Sub Process_Globals
Dim x,y,z As Int
End Sub
Sub Activity_Create(FirstTime As Boolean)
For x = 1 To 3
For y = 0 To 2 '<--- Change this from x to y for example and I would have made this 1 to 3 - just easier to read
z = z + 1
Next
Next
Log("z :" & z)
End Sub
This is untested code - so I'm trusting that my coding is OK.
