Get all rows value for one column

I have a table with a few colums, and i need to show when i open the page the total of all rows in one column.

Column name in database “Available”
need to show it in my my label, but I am not sure how to tel it to use the label"labelInfoOfUnitsAvailable" to show the amount.

If you’re using Google Sheets or Airtable, just create a sum formula in the table and then get the value of that cell from Thunkable.

I am using webflow for my database, How does it work if you use the phone as database
