^^ Actually that's a little personal else I would've uploaded
So let me tell you what the problem
Say I read upto page 10 today and the next day I'm read upto page 21 & the 3rd I read
upto 26
So what's in the file is I put page 10 in day 1 the page 21 in day 2 (on day 2)
Then it should show me in pages read coloumn =11
But on day 3 when I enter 26 it should show me 26-21 ie 5 (Today pages -yesterday Pages) & that's what I want
Which isn't happening
I am unable to subtract today's pages from yesterday ones
The case is simple if you look with the fact that there are 2 days but it gets complicated if you look with 3 or more days
What I want is something that can subtract
today from yester day whether that's day 2-day1 or day 25-day 24
