We've created an item in the Product Window. Product's name is CPA.
In addition, in form "Opportunity Product Revenue" , we created a function in "Purchase Price" field. Days ago, that function worked succesfully, but today it's not working.
The function is: IIf([<ProductName>]= 'CPA', '3600', '1100'). We choose "CPA" in product field, and according to function, in "purchase price" field must refresh with value '3600'. But function returns '1100'.
