Q:

Making a master file

I have made this macro to combine 4 different call trackers into one master file.  My problem is that its only pulling info into the Master Tracker from Call Tracker and the Call Tracker SS and only the cases sheet.  
Not getting information from the Call Tracker Jess or Miri files at all nor is it populating the other tabs: Tasks, Notifications, Special Requests or Follow Up, from all the files into the Master Tracker. 
The weird thing is that I don't get any error.  the Macro runs imports the first two records in the Call Tracker and Call Tracker SS Cases file and stops...
Could someone please review the code and advise what I may be doing wrong?

A:

Start by adding Option Explicit at the top of your module and re-running your code. 
Eg:
Set wbCallTrackerJG = Workbooks. Open(Filename:="H:\BX-HR\BX-INDUSTRIAL RELATIONS\HR REPRESENTATIVES\PRIVATE\HRSSC\US &CA HD\Call Tracker Jess.xlsm")
If Not wbCallTrackerJess Is Nothing Then
  Set wsShCalls = wbCallTrackerJess. Sheets("Cases")
  wsShCalls. Range("A7:P" & wsShCalls. Range("A" & Rows. Count).End(xlUp).Row).Copy wsMaster. Range("A" & Rows. Count).End(xlUp).Offset(1, 0)
Else
  Exit Sub
End If

Here you're opening a workbook and setting to wbCallTrackerJG (an un-declared variable), but then checking the status of wbCallTrackerJess (which is declared).  Option Explicit would have hilighted that error for you. 
Note also that if your Open() fails then your code will raise an error, so checking for Nothing won't help you handle that case.
