Sum conditional values in column

[aprx]

The function below lets me sum the values of a column which can be submitted to filters.
sub.total(9;H2:H115)
How can it be modified to sum only a given value, 1 for example, of the column?
( I don't know how to insert the IF function).
Thank you,
aprx

Hi aprx,

If you select the autofilter and then select 1 from the drop down, then the subtotal result will only be for these items
