VBA / Macro help needed to auto update the data from another workbook

Hi Folks,

I have two workbooks first one is called "JobList.xlsm" and second one is "Workpack_Status_Tracker.xlsm". And, these are handling by two separate users.

I need a Macro to update some columns from "JobList.xlsm" to "Workpack_Status_Tracker.xlsm" and one column from "Workpack_Status_Tracker.xlsm" to "JobList.xlsm", if any changes made in the workbooks. Also I have a "Summary" sheet in "Workpack_Status_Tracker.xlsm" these also need to updated (details marked in the sheet).

I have attached an excel file of what I'm trying to accomplish. Thanks in advance for your expertise!
