OFFSET(range,row,col,height,width)
range: reference or range
row: number of rows to offset range
col: number of columns to offset range
height: height of the offset range, defaults to height of range
width: width of the offset range, defaults to width of range
OFFSET returns the cell range starting at offset (row,col) from range of height height and width width.
If range is neither a reference nor a range, OFFSET returns #VALUE!
