Hi tan'
You may want to reconsider the structure of your Spreadsheet document.
Much easier to use a single Data table (rather than 186 separate tables) on which to enter the data on and 31 Daily Summary sheets, each with six tables to extract and summarize the data for each day.
Using the setup you currently have, I'd start by renaming the Tables, using only the daynumber and table number, separated by a dash.
Sheet 1 would then contain these tables: 1-1, 1-2, 1-3, 1-4, 1-5, 1-6
Sheet 2 would contain these tables: 2-1, 2-2, 2-3, 2-4, 2-5, 2-6
Et cetera.
The formula for each total would look like this one (for the total of values in cell B3 of tables x-1)
=SUM(1-1::B3,2-1::B3,-1::B3,4-1::B3,5-1::B3,6-1::B3,7-1::B3,8-1::B3,9-1::B3,10-1::B3,11-1::B3,12-1::B3,13-1::B3,14-1::B3,15-1::B3,16-1::B3,17-1::B3,18-1::B3,19-1::B3,20-1::B3,21-1::B3,22-1::B3,23-1::B3,24-1::B3,25-1::B3,26-1::B3,27-1::B3,28-1::B3,29-1::B3,30-1::B3,31-1::B3)
Repeat for each of the totals required.
With your Sheets and Tables as currently named, each of these cell references would expand to include the full name of the Sheet and the name of the table on that sheet:
=SUM(Sheet 1::Table 1::B3, … ,Sheet 31::Table 1::B3) (with … replaced with all 29 other addresses in the list, separated by commas.
For an example of the type of formula possible when ALL transactions are recorded on a single Data table, take a look at the Summary by Categories table i the Personal Budget template in the Template Chooser.
