I want a value hidden if it is 0

[Jimboscomp]

I am making a invoice out of a spreadhseet using functions and the such.

I want to make the invoice kind of a "template" i guess you could say with
all the functions in there, just need to enter the values. And lets say I
don't have any items on lines 2-8, so I want the total amount to be 0, or
hidden.
Example: In Cell I-15, the function is "=F15*G15". In F-15 the value is 2,
G-15 the value is 65, because I did 2 hours at $65 per hour. In I-15 it comes
up and says $130.00. That's great. But what I wanted to know is if say I want
to enter the rest of the formulas down the invoice (I have 10 lines preset).
But IF I dont put anything in rows 16-25, then instead of $0.00 showing up in
Cells I-16 - I-25, it won't show anything. Is this possible? I can provide
the spreadhseet if you need better clarification. Thanks!

=IF(F15*G15=0,"",F15*G15)
it will show the result only if it is non-zero...

or you can have custom format as
0.00;(0.00);
This will show positive nos with two decimals, negative in () and supress 0.

Thank you both of you! That was a very big help and did exactly what I wanted
it to do. I'm a bit old school when it comes to managing finances on the
computer, I tried Quicken and Quickbooks and don't like them, so good old
Excel will do me just fine. Thanks!
