Help with the Spreadsheet

I've just been recording Gertrude's reading in a notebook. I would like to start recording on a spreadsheet on here. I've look at them and I'm very confused on how to record the information. Can anyone help me out?

 

Here's the instructions and information: http://www.felinediabetes.com/FDMB/threads/fdmb-spreadsheet-instructions.130337/ . It's not hard, here's column meanings:

AMPS - 'AM' (morning) Pre-shot test number
PMPS - 'PM' (evening) preshot test number
U - units given
The +1/+2/+3 etc is for the test number taken that number of hours since the shot was given. We're worldwide so saying 8am can be anywhere within a 24 hour period by time zone. Using the number of hours since shot lets everyone easily understand. There's coding that will automatically color the cell by the entered number.

Hope this helps!

 

Thank You!! I think I got it
