Hi!
I have built a system tracks medications and supplements used in my household, and lets me know when to refill and how much I need. I’m looking for an easy way to make corrections when the calculated amount leftover doesn’t match reality during the check.
More details:
It’s essentially an inventory system that uses preset consumption amounts to prompt me when to replenish the supply. When I check the supply each month, I find that occasionally the real consumption amount is different than predicted, and I need to adjust the number for the amount leftover before replenishment. However, that amount is calculated so I can’t adjust it manually.
Table details:
Each row includes the following columns (among others):
A. Name of Pill (Text)
B. Amount in container (#)
C. Number of loose pills on hand at start of month (#)
D. Number of containers on hand at start of month (#)
E. Total number of pills on hand at start of month (#ƒ C+D)
F. Amount used monthly (#ƒ calculated from other columns)
G. Total number of pills leftover at end of month (#ƒ E–F)
Example scenarios:
- I take 2 multivitamins a day, and the bottle contains 100 pills. At the end of the month (30 days) I should have 40 left (100-(2*30)), however, I forgot to take it a a few times so I actually have 45 left.
- My cat takes 1 calming pill per day, but I took her to the vet a couple times and used some extra ones. The bottle contains 90 pills for 90-day supply. When I tally up at the end of the second month, I see I have 25 left instead of 30.
In the first case I need to add to the ending total, and in the second I need to subtract.
Current approach:
What I’m doing now is adjusting the one number that can be manually entered (column C) which requires me to stop my inventory and do some math – not my strong suit.
What I want:
Ideally I would hit a button, enter the true amount leftover, and have a formula figure out the difference and adjust it.
How would you do this within a row?
Thanks in advance,
Amy
