Im making a sheet to have control over my investments.
To do this I'm making one table overlooking my buying history, and one where all my investment holdings show.
STOCK SHEET
What I want to do is to search the history table and add up all stocks in one row automatically in the inventory table.
Example:
Select all "how many" values from "history" where stock is equal to aapl.
In php this would return an array (I guess) and then I could add up all the values and display them. But this is not php and I don't know what this type of action is called.
Does someone have a solution to this and know what this action is called?
Thank you.
