increaseing row value in a function VBA

using a variable how would I increase the row

Range("Ml"). Value = "DELAY : 1967"
right now I have the variable "l" for it...but its not working

maybe something like

Sub tt()
Dim i As Long
i = 5
Range("M" & i).Value = "DELAY : 1967"
End Sub

hi Sparkplug

Sub test()
For i = 1 To 10
    Range("m" & i) = "DELAY:" & 1966 + i
Next
End Sub
