Paste Data Range given Target Row number

Hi everyone!
Thanks for the help in advance...

*Please refer to the uploaded sample-
So I have this worksheet in which:
> I have a set of Data Blocks (essentially a range of data) that I want to paste onto a target cell (Col Q to V).
> The target cell's Column is fixed as "B", while Row is given in Col K.
> For each of the give row number, there is a coresponding Block No. assigned. That Block (Data range) would have to be pasted into Cell B???, ??? as the given row number.

My explaination seems messy even to myself but since my english is very powderful...

Example (Row 4): Cell K4 = 4, Cell L4 = H1
> so... Paste Range Q3:V4 (size of Block H1) onto B4 ('B' being fixed, '4' from Cell L4)
> Repeat for next row (5 and onwards... to around 700?)
*There are a good number of blank rows within Column K & L too (in the complete list), please simply skip that row and carry on.

I have tried the following and of course it didn't work..

Sub Format_Now()

Set i = Intersect(Target_Assy, Range("$K$4:$K$20")) '4 to 20 (of 700 for testing)
Set j = Intersect(Target_PasteRow, Range("$L$4:$L$20")) '4 to 20 (of 700 for testing)
  If Not i Is Nothing Then
    Select Case Target
      Case "":
      
      Case "H1":
      Range("Q3:V4").Select
      Selection.Copy
      Range("B" & j).Select
      ActiveSheet.Paste
      
      Case "B1":
      Range("Q6:V7").Select
      Selection.Copy
      Range("B" & j).Select
      ActiveSheet.Paste
      
    End Select

End If

End Sub

Thanks for the help again!
