Sum/subtract Sharepoint

[Anonymous]

Hello,

On SharePoint I have two columns "Spent" and "Amount" and I would like to be able to do subtractions on a "Total" column but I can't get subtractions to work on the "Default" PowerApps box.

Is it possible ?

If so what is the procedure to follow please

Spent = 34

Ammount = 11

34 - 11 = 23

TOTAL column = 23.

Thanks you advance, GL.

One option is to create a calculated column in SharePoint if you want to store the value. If you want to display the value in App, then you can use the below expression:

Value(DataCardValue1.Text) - Value(DataCardValue2.Text)

Here, you need to replace DataCardValue1 with the control name for Spent and DataCardValue2 with the control name for Amount.

Hope this Helps!

Hi @Anonymous ,

What is the column type of your "Spent" and "Amount" column? Are they both Nmuber column?

Where do you want to display this "Total" column?

I assume your "Spent" and "Amount" column are Number column, and you want to display this “Total” column inside a DataTable. You can do the calculation inside PowerApps. I will give you the detailed steps about how to achieve this:

1. Create a new list called “subtract” with two Number column named “Spent” and “Amount”:

2. Go to your app and add a DataTable, set the Items property of this DataTable as below(remember to replace your own SP list name):

AddColumns(subtract,"Total",Spent-Amount)​

3. Go to the Properties pane of this DataTable, click “Edit fields” to add the new column added in step 2.

4. This time, check the results in your Data table:

If you create a new list item in SP list, and refresh your data source inside the app, you will see the new added record in the DataTable:

Note:

1. AddColumns() function don't modify the original SP list. Instead, it takes that table as an argument and return a new table with a transform applied. So you cannot see the new added columns in your SP list.
2. You can also use this formula in a Gallery if you want to display records in a gallery.

Best Regards,

Allen
