There could be an issue with that formula if the "old_formula" does not
return 1.
The IF function returns the If_False value only if the conditional test
equals FALSE or zero. For all other values the function returns the If_True
value.
(Note: if the conditional test results in an error, text or an empty string,
an error is returned)
Examples
=IF(-20,"Yes","No")....returns "Yes"
=IF(1,"Yes","No")....returns "Yes"
=IF(10=(2*5),"Yes","No")....returns "Yes"
=IF(FALSE,"Yes","No")....returns "No"
=IF(10=20,"Yes","No")....returns "No"
=IF(0,"Yes","No")....returns "No"
