Worksheets("Sheet1"

.Cells(10, 1) = "fred"
From here you can obviously then use other calculations to set the row/column number, which is useful if looping etc eg (Forget any logic as to what it is doing as it has just been snipped from another pice of code - Simply examples):-
Last used row:-
LstRow = Cells(Rows.Count, "A"

.End(xlUp).Row
or
Misc uses
i = Cells(Rows.Count, "B"

.End(xlUp).Row
j = Cells(Rows.Count, "B"

.End(xlUp).Row - 2
Set Rng = Range("I3:Z" & i)
For k = 0 To 5
Rng.Copy Range("D" & ((j * k) + i) + 1)
Next k
'Bring Down the US(A) Lab Hours
Set Rng = Range("B3:B" & Cells(Rows.Count, "B"

.End(xlUp).Row)
Rng.Copy Range("B" & (i + (j * 0) + 1))
Range("A" & (i + 1) & ":A" & (i + j)) = "A Lab"
'Bring Down the US(B) Lab Hours
Set Rng = Range("C3:C" & i)
Rng.Copy Range("B" & ((i + (j * 1)) + 1))
Range("A" & (i + (j * 1) + 1) & ":A" & (i + (j * 2))) = "B Lab"
'Bring Down the UK(A) Lab Hours
Set Rng = Range("D3

" & i)
Rng.Copy Range("B" & ((i + (j * 2)) + 1))
Range("A" & (i + (j * 2) + 1) & ":A" & (i + (j * 3))) = "C Lab"
