input box cancel excel vba - excel

Question

This code copies a block of excel data (Col A to Col BH), and prompts the user to select the row where the copied template needs to be pasted. The code seems to work just fine( feel free to clean up/optimize any code), my issue is whenever a user clicks cancel when they need to pick the row I get an error "run time error 13 type mismatch". Is there anyway to just end the macro if cancel is selected?
Sub CopyTemplate()
Worksheets("HR-Calc").Activate
Dim rng As Variant
Dim trng As Range
Dim tco As String
Dim hi As String
Dim de As String
'Use the InputBox select row to insert copied cells
Set rng = Application.InputBox("select row to paste into", "Insert template location", Default:=ActiveCell.Address, Type:=8)
startrow = rng.Row
' MsgBox "row =" & startrow
Range("Bm2") = startrow
Application.ScreenUpdating = False
'copy template block
Range("C6").End(xlDown).Select
Range("bm1") = ActiveCell.Offset(1, 0).Row
Worksheets("HR-CAlc").Activate
tco = "A6:bh" & Range("bm1")
Range(tco).Select
Selection.Copy
Range("A" & Range("bm2")).Activate
Selection.Insert Shift:=xlDown
Range("c100000").End(xlUp).Select
Selection.End(xlUp).Select
'mycell.Select
''Use the InputBox to select text to be replaced
''Set rep = Application.InputBox("select data range where text will be replaced", Default:=ActiveCell.Address, Type:=8)
'Set rep = ActiveCell
' Told = Application.InputBox("Find the text that needs to be replaced", "Find text in Input data", Default:=ActiveCell.Value, Type:=2)
' If Told = "" Or vbCancel Then
' End If
'
' Tnew = Application.InputBox("Input desired text", "Replace text in data", Default:=ActiveCell.Value, Type:=2)
' If Tnew = "" Or vbCancel Then
' End If
'
' rep.Select
' Selection.Replace What:=Told, Replacement:=Tnew, LookAt:=xlPart, _
' SearchOrder:=xlByRows, MatchCase:=False, SearchFormat:=False, _
' ReplaceFormat:=False
Range("bm1:bm2").ClearContents
SendKeys "{F2}"
SendKeys "{BS}"
Application.ScreenUpdating = True
End Sub

Answer 1

You still need error handling to detect the Cancel
Dim rng As Range '<~~~ change type so If test will work
'Use the InputBox select row to insert copied cells
Set rng = Nothing ' in case it was previously set
On Error Resume Next
Set rng = Application.InputBox("select row to paste into", "Insert template location", Default:=ActiveCell.Address, Type:=8)
On Error GoTo 0 ' or your error handler
If rng Is Nothing Then
' User canceled, what now?
Exit Sub 'maybe...
End If

Add these lines including error handler:
On Error Resume Next
Set rng = Application.InputBox("select row to paste into", "Insert template location", Default:=ActiveCell.Address, Type:=8)
On Error GoTo 0
If IsEmpty(rng) = True Then
Exit Sub
End If
These lines will exit the sub if it won't find any value for rng.
