How to create categories of cells so I can reference to them in other sheet?

[kiedis]

Hello,

I am trying to create a monthly budget sheet. It consists of 2 sheets. The first sheet consists of 2 columns - column EXPENSE_TYPE and column AMOUNT. An example:

EXPENSE_TYPE | AMOUNT
Travel 1007$
Food 300$
Utilities 54$

The second sheet is listing all the transactions that I made during particular month, so it has columns of DATE, EXPENSE_TYPE and AMOUNT. An example:

DATE | EXPENSE_TYPE | AMOUNT
20190901 Food 23$
20190902 Utilities 15$
20190903 Travel 315$
20190903 Food 22$

My goal is to bind the EXPENSE_TYPE and AMOUNT columns in Sheet1 and Sheet2, so that when I fill in data in Sheet2, the AMOUNT column with appropriate EXPENSE_TYPE row in Sheet1 is automatically updated. In my given example above, you can see that in Sheet2 there are 2 rows of Food expenses. So the sum of these expenses (23$ + 22$ = 45$) should automatically be calculated and displayed in Sheet1 column AMOUNT and row Food.

How can I do it? And maybe you could tell how this thing that I want to implement is called officialy? Binding? Referencing? Something else?

Thank you

Not sure I understand, but, in sheet1, on any cell, hit “=”, then go to sheet2 and enter the cell you want to show up in sheet1 to update, and hit “Enter”.

just noticed that some parts of my question were not formatted in the way that I intended. However, what I want to do is to create drop down menu for some cells. If you ever saw Monthly budget template on Google Sheets, there is certain a column called Categori and all rows under that column have dropdown menu where you can choose the category of expense. How could I create a similar drop-down menu in Libre Calc?

OK, I actually managed to create drop-down manu via Data → Validity. Now the only step left is to somehow bind the cells in different sheets so that when I make an entry in Sheet2, the total amount of expenses gets automatically updated in Sheet1. I tried to copy a formula from Google Sheets but it didn;t work:

=IF(ISBLANK(C6), “”, SUMIF(sheet1!$c:$c,$C6,sheet2!$d:$d))

This formula is in Sheet1 AMOUNT column C6 and it tries to catch the data from Sheet2 column C (EXPENSE_TYPE) and column D (AMOUNT)
