sum formula for same cell on multiple tabs

I'm wanting to add the value of B3 from each of 30 consecutive tabs, totaled on Tab 31. Is there a simple, shorthand way of expressing that, or do i have to add each one in a long string? Many thanks!

You can use something like

Formula:

=SUM(Sheet1:Sheet30!B3)

That was the first thing i tried, but it's not working, with our without parentheses around the sheet names.

In that case can you provide a sample workbook.

Attached is the book, thanks!

Thanks for that.
It should be

Formula:

=SUM('1:31'!B3)

That did it, thanks so much!

Glad to help & thanks for the feedback.
