actually you do .... I was thinking they were missing as well because I expected them at the bottom of the chart.
Everything is alphabetical, so if you look carefully at the 'buttons' on the software the entire BR1-13 triangles comes after row B1-13
and BLC - the bottom left corner.
BRC comes right after all the BR bottom row triangles. The top kites are located the same way, on either side of the TR triangles... TLC - then TR1-13 - then TRC
just remember that you name your squares triangles and kites just like Brenda.... mya1....alphabetically all the way to mytrc. I did think the same thing!
