Hi

I am having some trouble with the below expression in a query. I am trying to get the average of three fields which allows for zero's.

ACWLW: ([RELTTMALW]+[AOLTTMALW]+[WTMALW])/IIf((-([RELTTMALW]<>0)-([AOLTTMALW]<>0)-([WTMALW]<>0))

It is telling me that The Expression you entered has a function containing the wrong number of arguments.

It has been a long day and I just cannot see it!! Could somebody please enlighten me :-)

Thanking you
