VBA sub procedure

Attached please find the macrofile.

I'm trying to use the above procedure to fill a summary table that contains columns with values for input1,2,&3 and the output section which should contain calculated figures after applying calcmacro.

kindly assist.

Since you have had no reply i think maybe you need to be more specific regarding what you want. maybe create a tab looking exactly like you require.
Also some background as to what this is about might help.

try this run on the summary table sheet

Sub CalcMacro()
lastrowx = Cells(Rows.Count, "A").End(xlUp).Row
For j = 3 To lastrowx
    For i = 1 To 20
       Cells(j, i + 4) = (3 - i) * Cells(j, 2) + (2 + 2 * i) * Cells(j, 3) - Cells(j, 4)
    Next i
    Next
End Sub

you want something more like this?

Sub calcmacro2()
For i = 3 To 12
Sheets("CalcDummy").Range("B5").Value = Sheets("summary table").Range("B" & i).Value
Sheets("CalcDummy").Range("B6").Value = Sheets("summary table").Range("C" & i).Value
Sheets("CalcDummy").Range("B7").Value = Sheets("summary table").Range("D" & i).Value
Call CalcMacro
Sheets("summary table").Range("e" & i & ":x" & i).Value = Application.Transpose(Sheets("CalcDummy").Range("c11:C30"))
Next i
End Sub
