VBA Skipping lines of code.

I have already done some research and seen what people have posted in the past and I cannot find a solution to this problem. Here is my code. Its pretty simple and bare.

Sub namees()

For r = 1 To 1099

    For n = 1 To 315
      
        Debug.Print r & " " & "|||" & " " & n

        If Sheets("Sheet1").Cells(r, 13).Value = Sheets("Sheet2").Cells(n, 2).Value Then
        
            Sheets("Sheet2").Cells(n, 8).Select
            With Selection.Interior
            .Pattern = xlSolid
            .PatternColorIndex = xlAutomatic
            .Color = 255
            .TintAndShade = 0
            .PatternTintAndShade = 0
            End With
            Exit For
            
        End If
        
        If r = 1092 And n = 311 Then
        MsgBox "here"
        End If
        
    Next n

Next r

End Sub

You can test this code with 2 blank sheets. It never reads the If r = 1092 And n = 311 Then. Why does it do this? I mentioning this line because if it read this line, then it would execute the other if statement above. But it skips just about all of it, but counts correctly in debug.print.

Edit: Also, if I run the entire code using F8 then it works like it's suppose to.
