In M1 enter =K1-L1

Move the mouse pointer to the bottom right corner of M1.

You will see a black square lump.

Double-click on that lump to replicate the formula down as far as there is
data in column L.

=K1-L1 will be incremented to =K2-L2 and K3-L3 etc.

i have tried to do it by put the curser on the colmn so it highlightes all
the fields but this results in having the answer in row m1 and doesnt
update
all the rows.
