Conditional Calculatoins

[warneretal]

I have an excel spreadsheet that I got from colleague. This spreadsheet
will automatically calculate cells if a value has been entered. The
thing I can not figure out is that there is no formula in the cell
until values are entered. At that point Excel will put the formula in
the cell and a calculation is made.

Example.
A B C D E F G H
I
57 Jul-05 1 12 8 5 28 0 37 17
58 Aug-05
59 Sep-05

The formula in cell H57 is =B57+D57+F57

The formula in cell H58, H59, H60 etc. is blank. However, as soon as I
enter a value in cells B, D and F then the formula in H58 would appear
=B58+D58+F58.

My question: How does this work. I have been trying to figure it out
so I could change as I need to in the future.
