My problem is this, I have a sales graph for my sales people that needs to
collect daily sales per day. I enter the sales as they come in, in "sheet 1"
of the workbook (the graph is in "sheet 2"). These sales are then collated
into a total for the month - as the month goes by, this number grows. The
graph I have is a line graph that crawls along like a worm increasing as it
goes based on the number of sales for the month.

How do I create a formula that will look from one sheet to another, can
remain blank leading up to that particular day, pick up the value of that
cell on that day and then keep the value static the next day, then next days
cell then picks up the new sales total and so on.

I would imagine sosmething along the lines of "if less than 22/08/08 then ""
otherwise a1, if greater than 22/08/08 then remain static"?

What i need to happen is that the sales value on that particular day stays
at that value as the month goes by so that i can create a creeping graph of
sales for the month.

Hopefully this makes sense - happy to clairify further if you like.
