IF IS nothing then count

Question

I want to create statement such as

=IIf(IsNothing(Fields!Amount.Value)),0,(Sum(Fields!Amount.Value)/1)

but from some reason it does not work. It should check value if it is null. If it's null, just enter 0, if it is not null, just make the calculation.

What am I doing wrong here? I am getting error for the first part of "IsNothing" code which says "Wrong number of arguments" but I do not see the error.

Found it.

=IIf((IsNothing(Fields!Amount.Value)),0,(Sum(Fields!Amount.Value)/1))

Just missed brackets.
