I'm trying to keep a running sum of the amount of liquid we are holding for our business's transfer log and I am not even sure where to begin!
We have to log transfers (IN) and (OUT) and I would like to write a formula to keep up with this if possible. (Adding the amount in rows with IN and subtracting the amount in rows with OUT)
I have a column that contains the amount of liquid per transfer [Quantity (gal)], and a column that contains phrases and keywords to indicate transfer IN or OUT [Reason for Opening Container].
I have attached a screenshot of the columns for reference.
