How to stop code from debugging/ keep notifying me that only the top left value will be?

Sub MI_Merge_FV()
Dim i&, k&: k = 1
For i = 1 To Cells(Rows.Count, 2).End(xlUp).Row
    If Left(Cells(i, 2), 1) = "T" Then
        Cells(k, 1).Resize(i - k).Merge
        k = i + 1
    End If
Next i
End Sub

How Do I stop the code from telling me that only the top left value will remain and go in to debug mode when there is nothing to merge?
