Help needed counting across sheets

Hi all,

I am trying to use the count of a symbol across some sheets. I know I can get this information by creating a report but for a more visual presentation, I am looking to get an actual number.

I am currently trying something like this but it's not working:

=COUNTIFS({sheet 1 Range 1}, 1, {Sheet 2 Range 2}, 1)

The symbol is a flag and I just want the count of the ones on across the sheets.

Thank you for any help and direction here,

Best,

Jose
