Hi Beni,

Many thanks, Have just slotted it in before units and data within the centreline/endcentreline wrapper, and it works!

Thank you for helping me get this sorted.
 on your recommendation, I have not included an endgrade as there is no need.

Just realised you're the master of grades Beni :) https://mailman.speleo.sk/pipermail/therion/2016-November/006103.html
