Question on VBA code

Hello,

can someone explain this code to me? I have this file that has a macro button transferring all the information(KPI's to be exact) from a database worksheet to a viewing worksheet. On the viewing worksheet, you select a name of an employee and when you press the "load data" button, it transfers all the KPI for that specific employee. Any help would be great.

Private Sub cmdLoad_Click()
Dim i, j As Integer

j = wksPMP.Cells(4, 4) + 2

For i = 23 To 34
wksPMP.Cells(i, 3) = wksDatabase.Cells(j, i - 20)
Next i

For i = 40 To 51
wksPMP.Cells(i, 3) = wksDatabase.Cells(j, i - 25)
Next i

For i = 57 To 68
wksPMP.Cells(i, 3) = wksDatabase.Cells(j, i - 30)
Next i

For i = 74 To 85
wksPMP.Cells(i, 3) = wksDatabase.Cells(j, i - 35)
Next i

For i = 23 To 34
wksPMP.Cells(i, 8) = wksDatabase.Cells(j, i + 28)
Next i

For i = 40 To 51
wksPMP.Cells(i, 8) = wksDatabase.Cells(j, i + 23)
Next i

For i = 57 To 68
wksPMP.Cells(i, 8) = wksDatabase.Cells(j, i + 18)
Next i

For i = 74 To 85
wksPMP.Cells(i, 8) = wksDatabase.Cells(j, i + 13)
Next i

For i = 91 To 102
wksPMP.Cells(i, 3) = wksDatabase.Cells(j, i + 8)
Next i

End Sub

Private Sub cmdSave_Click()
Dim i, j As Integer

j = wksPMP.Cells(4, 4) + 2

For i = 23 To 34
wksDatabase.Cells(j, i - 20) = wksPMP.Cells(i, 3)
Next i

For i = 40 To 51
wksDatabase.Cells(j, i - 25) = wksPMP.Cells(i, 3)
Next i

For i = 57 To 68
wksDatabase.Cells(j, i - 30) = wksPMP.Cells(i, 3)
Next i

For i = 74 To 85
wksDatabase.Cells(j, i - 35) = wksPMP.Cells(i, 3)
Next i

For i = 23 To 34
wksDatabase.Cells(j, i + 28) = wksPMP.Cells(i, 8)
Next i

For i = 40 To 51
wksDatabase.Cells(j, i + 23) = wksPMP.Cells(i, 8)
Next i

For i = 57 To 68
wksDatabase.Cells(j, i + 18) = wksPMP.Cells(i, 8)
Next i

For i = 74 To 85
wksDatabase.Cells(j, i + 13) = wksPMP.Cells(i, 8)
Next i

End Sub
