Something to add about trimming multiple lines - Another scenario is if you extract values from another table say the search type is Transaction Search filter is Type = Sales Order and then you are pulling up let's say the total RMA amount associated to the SO, if you are using the Applying transactions link and the SO may have more than 1 applying transaction like, Invoice , Item Fulfillment, and RMA - use the Applying Link type as criteria filter. 🙂
