Use Active Cell For Row Number

There is a chart encompasing column A, B and C. The column D has certain numbers stored in its cells. All I wont is to build a code which would check the value of the cell in column D which is in the same row as the active cell, and then paste certain date into the active cell - basing on the value of the cell in column D.

Here an example:

Sub pasteif()
first one) column D has
'if the value is i.e 2 then it should paste into the active cell whatever there is in Range F1:G1
'if other value is present in this case in cell D1 (it is always the D column) then other range would copied into the active cell
Range("F1:G1").Copy
ActiveCell.PasteSpecial Paste:=xlPasteValues, Operation:=xlNone, SkipBlanks _
:=False, Transpose:=False
End Sub
