How to return a certain value at formula when the reference field is blank?

if field(‘countBarSuspend’) < ‘2’ then this > 50
else this < 50

some field(‘countBarSuspend’) is blank but I receive this error: Could not access blank value: Use || to provide a default value for blank fields. Example: (my_field || 0) + 1

I want the field(‘countBarSuspend’) < ‘2’ and blank to return value > 50

Is this what you are looking to do?
