how to use variable in set analysis

[pallabi_jor]

Hi all,

variable= sum(Cost)/ sum( SellingPrice) //  -- result  is in percentage

I need to display the count of product whose percentage is equal to 5.5%

= count( {<$(=$(Variable))={'5.5'}>}Product)

I am writing above expression, but not getting  correct answer

Thanks

Hi. Try this

count( {< Product = {"=sum(Cost)/sum(SellingPrice)=0.055"}>} Product)
