Default empty cell as a result of IF formula

but i cannot use this result in a SUM formula


Perhaps you want:

=if(condition, "", SUM(range))

Note that this does not result in an "empty cell" per se. In particular, if
that formula is in A1 and it results in "", ISBLANK(A1) will be false(!).

A formula can only result in the null string, which makes the cell
__appear__ empty or blank. You can detect truly empy (no formula or
constant) or null string by testing A1="".
