I have a field on my report called birthday, I have a need to display the persons age on the report.

How does one go about that?

I already have a function in my application called calcAge which takes an input and returns the persons age.

Just dont know how to use it in my CR.

Thanks

You can't use a function in an application to do this unless the function is in the database, in which case it can be called either in the select statement of a command or, if you're using just tables/views on your report, you can create a SQL Expression that will call the function.
 
If this is not in your database, you'll need to recreate the logic for it in a Crystal formula.

I ran into this problem and created a variable called age today.  The way it works is to subtract Date_of_birth from Current_date.  This returns the number of days someone has lived.  Then I divide that by 365 (yep I ignore leap years) which give me a number with lots of decimals.  The next step if to kill those decimals, so round the number up and subtract 1. 
 
Here is the code:   Roundup((CurrentDate - {patient_current_demographics.date_of_birth}) / 365)-1

Opps I mean 365 not 360 in the formula

I ended up doing almost exactly like you did. Worked like a champ.
Someone told me to put the .25 because of leap year.

INT((CurrentDate - {AddTenants.Birthday}) / 365.25 )
