If (search term) found, do (action). If not, end if - vba

Question

If you guys could help me out, that would be great because it would really help me.
Here's what I'm trying to do:
Search for a cell with a specific term
If found, copy the entire row that the cell is in and paste it into a row above it.
If not found, do nothing and continue with the code
Here's my code:
Sub Test()
'
' Test Macro
'
' Keyboard Shortcut: Ctrl+b
'
Range("A5").Select
Cells.Find(What:="PL 1", After:=ActiveCell, LookIn:=xlFormulas, LookAt _
:=xlPart, SearchOrder:=xlByRows, SearchDirection:=xlNext, MatchCase:= _
False, SearchFormat:=False).Activate
If Not IsEmpty(ActiveCell.Value) Then
ActiveCell.Rows("1:1").EntireRow.Select
Selection.Copy
Range("A5").Select
ActiveSheet.Paste
End If
Range("A5").Select
Cells.Find(What:="PL 2", After:=ActiveCell, LookIn:=xlFormulas, LookAt _
:=xlPart, SearchOrder:=xlByRows, SearchDirection:=xlNext, MatchCase:= _
False, SearchFormat:=False).Activate
If Not IsEmpty(ActiveCell.Value) Then
ActiveCell.Rows("1:1").EntireRow.Select
Selection.Copy
Range("A6").Select
ActiveSheet.Paste
End If
Range("A5").Select
Cells.Find(What:="PL 3", After:=ActiveCell, LookIn:=xlFormulas, LookAt _
:=xlPart, SearchOrder:=xlByRows, SearchDirection:=xlNext, MatchCase:= _
False, SearchFormat:=False).Activate
If Not IsEmpty(ActiveCell.Value) Then
ActiveCell.Rows("1:1").EntireRow.Select
Selection.Copy
Range("A7").Select
ActiveSheet.Paste
End If
End Sub
My code only works if the value is found. If it's not found it runs into the error below:

Answer 1

Cells.Find is a function that returns a Range object reference; when it doesn't find anything, the reference will be Nothing. And you can't call .Activate on Nothing:
This method returns Nothing if no match is found. The Find method does not affect the selection or the active cell. (MSDN)
Cells.Find(What:="PL 2", After:=ActiveCell, LookIn:=xlFormulas, LookAt _
:=xlPart, SearchOrder:=xlByRows, SearchDirection:=xlNext, MatchCase:= _
False, SearchFormat:=False).Activate
You need to rewrite your code and avoid .Select and .Activate, and avoid working with ActiveCell and implicitly with ActiveSheet (which you are doing by not qualifying the Cells call with a proper worksheet reference).
Your formatting makes it hard to read the code, for several reasons:
Arguments are being specified on different lines
Line continuations are being palced at arbitrary locations
Nested member calls aren't lined up
Compare to:
Cells.Find(What:="PL 2", After:=ActiveCell, LookIn:=xlFormulas, _
LookAt:=xlPart, SearchOrder:=xlByRows, SearchDirection:=xlNext, _
MatchCase:=False, SearchFormat:=False) _
.Activate
That's just readability. The problem is that you basically assume that .Find returns a valid object reference. Don't assume, explicitly check:
Set result = Cells.Find(...)
If Not result Is Nothing Then result.Activate
But really, you need to figure out a way to avoid .Select and .Activate.

Answer 2

You can try something like this instead (untested):
Sub HideAndSeek()
Dim foundCell As Range
For i = 1 To 3
Set foundCell = Cells.Find(What:="PL " & i, LookIn:=xlFormulas, LookAt:=xlPart)
If Not foundCell Is Nothing Then
Intersect(foundCell.EntireRow, ActiveSheet.UsedRange).Offset(-1, 0).Value = _
Intersect(foundCell.EntireRow, ActiveSheet.UsedRange).Value
End If
Set foundCell = Nothing
Next
End Sub
The principle being that you write the code you need once and then create a loop to repeat the code for you.
The other part of this answer is checking that the cell was found - to do this we check that the range was actually set (which means it isn't Nothing) using
If Not foundRange Is Nothing
