If cell is greater than X and less than Y input Z VBA

Hi,

Can someone take a look at my macro and let me know which part is wrong as only the "error" and the "30+" is coming out.

Sub advancebooking()

Dim lRow As Long

Sheets("7raw").Select

lRow = Range("t" & Rows.Count).End(xlUp).Row

For i = 2 To lRow

    
    If Cells(i, 21) >= 0 And Cells(i, 54) <= 2 Then
        Cells(i, 62) = "0-02"
    ElseIf Cells(i, 20) >= 3 And Cells(i, 54) <= 7 Then
        Cells(i, 62) = "3-07"
    ElseIf Cells(i, 20) >= 8 And Cells(i, 54) <= 14 Then
        Cells(i, 62) = "8-14"
    ElseIf Cells(i, 20) >= 15 And Cells(i, 54) <= 21 Then
        Cells(i, 62) = "15-21"
    ElseIf Cells(i, 20) >= 22 And Cells(i, 54) <= 30 Then
        Cells(i, 62) = "22-30"
    Else
        Cells(i, 62) = "30+"
    End If

Next i

End Sub

Thanks in advance!
