I'm using JSON for running through line items connected to a Sales Order

I'm unclear on what that means

Ha @erictgrubaugh I'm probably explaining it all wrong but i'll try again. I'm using {#each recordname} fieldname {/each} and it runs every line item and displays the "fieldname" for each item. I'm wondering if instead of #each there might be a way to just pull the most record line item or a specific line item. Hope that makes sense
