What this expression does is, when top 15 & bottom 15 physicians are selected, then the user cannot select more than 1 product. whereas on all other selections user should be able to select multiple products and '("'&GetFieldSelections([Brand Name],'"|"')&'")'
expression comes into picture.
This expression works fine, but the problem is when the brand name has spaces in between it acts wierd. Say a user selects brand: "ABC XY" and brand "EFG", then at the first instant user can see the data for both of the selected products, but when the user selects anything else, say changes time period on report etc the brand selection with space, i.e "ABC XY" goes off and user can see data only for brand "EFG".
