Views, like EditText , belong to an Activity so you cannot declare them in Process_Globals but only in Globals.
What you can do is transmit the EditText as a parameter in a sub call.

Pass the view to the sub:

B4X:

Sub beregne(et As EditText)
 areal = et.Text
End Sub

Try this code:

B4X:

Sub Button1_Click
   Trykk.bergne(EditText1)
End Sub

Code module, Trykk

B4X:

Sub bergne(edt as EditText)
   Dim areal As int
   areal=edt.text
........................
End Sub

Best regards.

Can you not also acces them from a code module like:

B4X:

main.MyEditText.Txt = "What I want Here"

Activity objects "die" when the Activity is closed(Activity.Finish). Therefore, you can't access them this way. You should reverse your logic (access CodeModules from Activities).

Code module:

B4X:

Sub doIt(txt as EditText)
    txt.Text = "My value was set by the CodeModule doIt() method"
End Sub

In your Activity:

B4X:

'In Globals:
Dim theField as EditText

'In Activity_Create or wherever
CodeModuleName.doIt(theField)

Another examples have been posted above by Erel and Klaus.
