copy data from userform to sheet are not correct in location

Hello 

I try copying  data  from  userform to  sheet INV_PUR . so  when  select  combobox "CODE" will fill  the  others  comboboxes  and  fill the  item by  serial number and write  the  values  manually in textbox(QTY), textbox(PRICE)  will calculation in textbox TOTAL   and  when  move  to next row  on  user  form to  select another  item by select combobox  (CODE) will do  the  same  thing , after  filling on userform should  copy  to  sheet INV_PUR  from row 19 . my  problem ignores   the  numbers   in textbox (ITEM) on userform  ,should  copy  to  column B in sheet INV_PUR from row 19  instead  of  that , will copy starting  combobox(CODE)  and  clear words  TOTAL,SUBTOTAL ,TAX   when  try  copy  data to sheet .

so I  put  the  expected result  after filling  data on userform in last   sheet  how  should  be .

Private Sub CommandButton5_Click()
  With Sheets("INV_PUR")
 For i = 1 To 11

         .Cells(i + 18, 2).Value = Me.Controls("TextBox" & i)
      Next i

      For i = 12 To 44
        .Range("F19").Offset((i - 12) Mod 11, Int((i - 12) / 11)).Value = Me.Controls("Textbox" & i)
      Next i

      For i = 2 To 45
''
         .Range("B19").Offset((i - 2) Mod 11, Int((i - 2) / 11)).Value = Me.Controls("ComboBox" & i)
      Next i
   End With
End Sub
