answer but I appreciated it - thanks very much for the quick response.

Could you explain what the = rows.count does?

I have the following code.

Selection.DataSeries Rowcol:=xlColumns, Type:=xlLinear,
Date:=xlDay, _
Trend:=True
Selection.End(xlDown).Select
Loop

How do I make the loop stop when the selection doesn't find any more
data?
At the moment it just goes to the bottom row of the workbook and fails.

appreciated!

Many thanks
