Sometimes my users know a person’s birthdate, and sometimes they only know their age, and sometimes they dont know either value and they will leave both fields blank.
I have a birthdate field, and an editable age field with an initial value based on the birthdate.
I am using the following formula for the initial value (slightly modified from another post here, thank you).
The data type of the age field is number.
If a user types in an age, I want to limit their input to integers only.
=if(isnotblank([Fecha Nacimiento]),
if(
month([Fecha Nacimiento])>month(today()), year(today())-year([Fecha Nacimiento])-1,
if(
and(
month([Fecha Nacimiento])=month(today()),
day([Fecha Nacimiento])>day(today())
),
year(today())-year([Fecha Nacimiento])-1, year(today())-year([Fecha Nacimiento])
)
),"" )
Note that I am using two double quotes to indicate that the field should be left blank if no birthdate is available to calculate a value.
However the field defaults to 0 instead of blank.
If I save the record without clearing the field, the 0 is saved.
What can I put instead of two double quotes to default the field to blank instead of zero?
