I frequently create a navigation subform which has the Prev/Next links. I toss this subform at the top and bottom of the $$ViewTemplate form. In R6, if you try to put the same subform twice on the same form, you’ll get an error message. (Apparently, they think “shared code” means it has to be shared among multiple design elements, not used multiple times on the same design element.)
To get around this, I define the subform as computed. For the formula, it’s the same subform. Notes doesn’t mind that.
