Merging Cells Where Row Is Variable In VBA

Merging cells where the row is a variable. The code has two loops that consolidate date from two other sheets, it works fine but as you can see it puts the data into columns A,B and C,D respectively. My goal is to combine both into the A,B columns, which I can do very easily. My problem is that between the loops, marked by "HERE" i want to skip a line, merge cells A and B on whatever row that maybe and set an header.

Code:
Workbooks("Discovery Errors.xls").Sheets("Totals").Range("A3:U60000").EntireRow.Delete
Workbooks("Discovery Errors.xls").Sheets("Totals").Range("A3:U60000").EntireRow.Font.Bold = False

ActiveWorkbook.Sheets("Disc_Nodes").Activate
ActiveWorkbook.Sheets("Disc_Nodes").Range("A1:U60000").Sort Key1:=Range("J1"), Order1:=xlAscending, Header:= _
xlYes, OrderCustom:=1, MatchCase:=False, Orientation:=xlTopToBottom, _
DataOption1:=xlSortTextAsNumbers
LastRow = Cells(Rows.Count, 1).End(xlUp).Row
