Vba Code to find value and paste on certain row

I'm am very new to vba and I have a excel sheet that has roughly 200 names, agent id and their role. I am trying to write a vba code to search for a Name via input box and paste All occurance of that name at the top of the sheet starting at row 3 and then insert a black line between the search data and existing data. Example I input "Jen" and copy every row that "Jen" occurs and inserts a row at row 3 and inserts the copied data moving existing data down. I have included what i have so far.I have pieced it together from codes that i have found online. I don't think it is totally correct. As my cancel button doesn't work and if the person searching leave it empty it still tries to copy data. Any help would be grateful.

Code:

---

Dim LSearchValue As String
Dim RefCount As Integer

Application.ScreenUpdating = False

LSearchValue = InputBox("Who do you want.", "Enter name") & "*"

Rows("3:3").Select
Selection.Insert

RefCount = Application.WorksheetFunction.CountIf(Worksheets("agent").Range("A:C"), LSearchValue) - 1

Range("A2").Activate

For Counter = 0 To RefCount Step 1

With Columns("A:C").Find(What:=LSearchValue, After:=ActiveCell, LookIn:=xlFormulas, _
LookAt:=xlPart, SearchOrder:=xlByRows, SearchDirection:=xlNext, MatchCase:=False, SearchFormat:=False)

Rows("3:3").Select
Selection.Insert

.EntireRow.Copy Destination:=Worksheets("Agent").Range("a3")
.Activate

  End With
Next


Application.ScreenUpdating = True

Application.Goto Reference:=Range("a1"), Scroll:=True

Why don't you use the autofilter ?

Ok I could do that if it is easier, can you share how that would work and code.... Like I said very new to this.

You can perform any search in this or similars forums using 'autfilter' to look for.
