Two activities - problem with the 'global'

[SteveBee]

I have read the tutorial re. Two Activities, but am having a problem implementing it.

My Main is a ListView; I have this in the itemclick handler:

Sub ListView1_ItemClick (Position As Int, Value As Object)
    JobViewID = value                            'store the value in the process global object.
    StartActivity(JobForm) 
End Sub

Note that JobViewID is a global:

Sub Process_Globals
   'These global variables will be declared once when the application starts.
   'These variables can be accessed from all modules.

   Dim parser As SaxParser, JobViewID As String
End Sub

So, when the listitem is touched, I expect the Jobform to load; in its create sub, I have:

Sub Activity_Create(FirstTime As Boolean)
    Activity.LoadLayout(("JobForm")
    Activity.Title = Activity.Title & "  " & JobViewID
End Sub

But when I try to compile I get a warning re. the 'global':
Compiling code. Error
Error parsing program.
Error description: Undeclared variable 'jobviewid' is used before it was assigned any value.
Occurred on line: 17
Activity.Title = Activity.Title & " " & JobViewID

I thought I had emulated the example, and I did put my link var. ("JobViewID") in the global section, but it doesn't link. It did seem a strange way of doing things... but that was what it said in the tutorial (in my reading).

Can you clear up my misunderstanding?

Steve

To access a Global in a module other than the one in which it is declared you need to prefix the module name - Main.JobViewID.

We just had this discussion on here in the last day or so, and it is now shown in the B4A Documentation Wiki.
