Userform for combolist/timestamp and commments code

I am trying to create a leave calendar that will allow individuals to view data enter from the 'LeaveData' tab dynamically in the Leave Planner Dashboard tab. The information will be entered from the schedule change userform and I have managed to get the date and employee name to auto populate. I am having the hardest time trying to get my combolist to auto populate from the 'Guide' tab under the Leave Req List. When an option is chosen I want the word to populate in the leave data tab. I would also like to have the comments and a timestamp w/ initials if possible. I am lost and don't know what to do. If anyone could provide me with some assistance on how I can get this thing together it would be a great help!

Where do you intend getting the initials from?
