If in expression

[#1]

I have the following expression.  See below.  But I only want that expression to work when the SalesAmount is > 0, How can I write this?

(Sum({<YearlyTotal = {[Year 3]}>}SalesAmount)/156)/count(DISTINCT ItemNumber)

[Gysbert_Wassenaar]

(Sum({<SalesMount={'>0'},YearlyTotal = {[Year 3]}>}SalesAmount)/156)/count(DISTINCT ItemNumber)

@Gysbert, imho you need "  instead of ' around the >0 (it's a search string):

(Sum({<SalesMount={">0"},YearlyTotal = {[Year 3]}>}SalesAmount)/156)/count(DISTINCT ItemNumber)
