Append cell to a different cell - excel

Question

I Have a Column C that has names in all its cells and another Column E that has the same company name in all its cells I need to append the names in Column C to the company name in column E
Thanks
Ex:
ColC ColE
Bob SampleCo
Sally SamplCo
I get
ColC ColE
Bob SampleCo Bob
Sally SamplCo Sally
I am trying but failing with
Sub CompanyName()
Dim LastRow As Long
Dim Ws As Worksheet
Dim rRange As range
Set rRange = range("E2")
rRange.Select
Set Ws = Sheets("WP_SubjectList_Ready")
LastRow = Ws.range("F" & Ws.Rows.Count).End(xlUp).Row
Ws.range("E2:E" & LastRow).FormulaR1C1 = "=rRange &RC[-1]"
range("E2:E" & LastRow).Copy
range("E2:E" & LastRow).PasteSpecial xlPasteValues
End Sub

Answer 1

Code
Sub CompanyName()
Dim LastRow As Long
Dim Ws As Worksheet
Set Ws = Sheets("WP_SubjectList_Ready")
LastRow = Ws.Range("E" & Ws.Rows.Count).End(xlUp).Row
Ws.Range("F2:F" & LastRow).FormulaR1C1 = "= RC[-1] & "" "" & RC[-3]"
End Sub
If you want the output in Column E its not possible using FormulaR1C1.
Any formula which work for excel interface will work for FormulaR1C1.
With that i mean (considering the image) in cell F2 you can manullay enter a formula = E2 & " " & C2 which will give you desired output. But if you enter in cell E2the formula as =E2 & " " & C2 the cell E2 will loose its value and this may even lead to circular reference issue.
It can be achieved using below code.
Sub CompanyName()
Dim LastRow As Long
Dim Ws As Worksheet
Dim rng As Range, cell As Range
Set Ws = Sheets("WP_SubjectList_Ready")
LastRow = Ws.Range("E" & Ws.Rows.Count).End(xlUp).Row
Set rng = Ws.Range("E2:E" & LastRow)
For Each cell In rng
cell = cell & " " & cell.Offset(0, -2)
Next
End Sub

Here's some code that should help you with what you want...I don't typically use ranges for loops because it's easier to use .Cells(row, col) for me, but anyways:
EDIT: Added Sub Opening/Closing Syntax and edited to use WS instead of ActiveSheet so it's closer to what you want
Sub CompanyName()
Dim WS as Worksheet
Dim vRow
Dim vRowCount As Integer
Set WS = Sheets("WP_SubjectList_Ready")
'Gets Row # of Last Row for Column E
vRowCount = Range("E" & Rows.Count).End(xlUp).row
'Assuming Both Columns have the same row count and you have a header row
For vRow = 2 To vRowCount
WS.Cells(vRow, 5).Value = WS.Cells(vRow, 5).Value & " " & WS.Cells(vRow, 3).Value
Next vRow
End Sub
