Macro offset using the value in a cell

[StephenT]

Hello,

I am looking to Copy a cell then paste n rows lower. I would like this
number n to be a value in a cell. i.e. If cell A1 = 2, then copy B1 two rows
lower (i.e. to B3). If cell A1=4, then copy B1 four rows lower (i.e. to B5).

I know offset ( , ) should be used for this, but as a novice I don't seem to
be able to put the cell reference in i.e. offset (A1,0)

Any help would be appreciated!
thanks
