Thread: Help with Automated Calculations after Copy and Paste

Hi All
I have a Spreadsheet that has the ability to have data entered manually with a trigger point and all my calcualtions work great.
Instead of manually entering my data now. I set up a macro to import large amounts of data.
The probelm I'm having now I can Not get the automatic calculations to work?
I'm using the following code to copy and past from Sheet1 to JeffsTransp
This Code Works
'B=B C=C D=D E=E F=L G=E H=F I=G K=H L=I M=J N=O T=M.
Application.EnableEvents = False
r = rngCell.Row
'u = Sheets("JeffsTransp").Range("B" & Rows.Count).End(xlUp).Row + 1
Sheets("JeffsTransp").Rows(u & ":" & u).Insert Shift:=xlDown
Sheets("JeffsTransp").Range("B" & u) = Sheets("Sheet1").Range("B" & r)
Sheets("JeffsTransp").Range("C" & u) = Sheets("Sheet1").Range("C" & r)
Sheets("JeffsTransp").Range("D" & u) = Sheets("Sheet1").Range("D" & r)
Sheets("JeffsTransp").Range("F" & u) = Sheets("Sheet1").Range("L" & r)
Sheets("JeffsTransp").Range("G" & u) = Sheets("Sheet1").Range("E" & r)
Sheets("JeffsTransp").Range("H" & u) = Sheets("Sheet1").Range("F" & r)
Sheets("JeffsTransp").Range("I" & u) = Sheets("Sheet1").Range("G" & r)
Sheets("JeffsTransp").Range("K" & u) = Sheets("Sheet1").Range("H" & r)
Sheets("JeffsTransp").Range("L" & u) = Sheets("Sheet1").Range("I" & r)
Sheets("JeffsTransp").Range("M" & u) = Sheets("Sheet1").Range("J" & r)
Sheets("JeffsTransp").Range("N" & u) = Sheets("Sheet1").Range("O" & r)
Sheets("JeffsTransp").Range("T" & u) = Sheets("Sheet1").Range("M" & r)
Application.EnableEvents = True
u = u + 1

I Can Not Get This Calculation to Work.? it works when the data is manually entered to trigger the trigger point.
Application.EnableEvents = True
Application.Calculation = xlAutomatic

Cells(Target.Row, 1).Formula = "=A4+A15+1"
Cells(Target.Row, 14).Formula = "=K16*L16"
Cells(Target.Row, 16).Formula = "=K16+N16"
Cells(Target.Row, 18).Formula = "=SUM(K16+O16)*Q16"
Cells(Target.Row, 20).Formula = "=R16*S16"
Cells(Target.Row, 21).Formula = "=SUM(P16-R16-T16)+M16"

Application.ScreenUpdating = True
Exit Sub

What is the best way to automate the Calculations with the Copy and Paste Code?

any Help that can be offered would be greatly appreciated
