Are you looking for this?:

In the manual:

    if("$1" == "nan" || "$2" == "nan", string(""), $1 + $2); E

    Sum of the first two columns. When at least one of the input
    fields is empty the Org table result field is set to empty.

In action: Look at the page with the Worg tutorials and in the
spreadsheet section follow the link to the "Emacs Regression Test
(ERT) for Org tables" with example use cases for TBLFM:
In the ERT it is test-org-table/empty-field, specifically "Test if
several fields are empty, else do a calculation".

I can't follow, maybe because I don't use clocking. Maybe you want to
use the hierarchical sum of a property in column view, here the
property "Effort". See
