oops, I see you do have your July point post all done and updated!
I probably gave you WAY MORE information than you needed, sorry.....
I fixed up your post for you.....
you tally your July points like you did, you add one point to that, that gives you your July points total.
then you add the PREVIOUS MONTH's POINTS
so you have 12 points so far.....
the way you had it was fine too but totals are always best.
to link to your previous post, you go to that post, and you click on the number at the top right of your post...

you can just paste the link.
