array formular

hi,

could you please look at the attached file

column a and b and row 14 and 15 could be a lot longer
and as you can see thwe formular in l15 could be a lot longer
is there an easier way to do this.

thank you
steve

Why dont you do it like this, and just insert rows and copy the formula
down (by dragging with your mouse) ?

Does this help you ?

thanks
steve
