Question

How do I include or exclude a person within a date range with just a person's birth date and today date?

 I need to set this formula up over six potential date ranges that a person's record in the database could fall into. The only null condition I can think of is if a data entry person forgets to put the birthdate in the persons record during the intake process.

    Can you say in words what the 6 ranges are?

    Here's the ranges:

    0-11

    12-15

    16-24

    25-34

    35-44

    45-54

    55 and over. That's a total of seven age categories. I missed the last one in the original count.

    Try this are a formula text field 

    var date DOB = [DOB]; // put your date of birth field here

    var number AGE =
    Year(Today())-Year($DOB)
    -
    If(
    Month(Today())<Month($DOB)
    or
    (Month(Today())=Month($DOB) and Day(Today())<Day($DOB)),1,0);


    IF(
    isNull($DOB), "  Missing D.O.B.",
    $AGE <= 11, " 0-11",
    $AGE <= 15, "12-15,

    etc

    $AGE >=55, "55+")
    OK, I will give it a shot and let you know how it worked. Thanks so much. I would have never figured this out on my own!
    OK, it works! I never used a variable before. I think I learned something today, hopefully. Thanks for your help! I would have never of been able to get this without direction!
    Formula variables are wonderful ways to make formulas more readable and easier to maintain.
    Yes, thanks to your input I just learned a valuable tool that I will try to apply as I chunk forward on my development. Again, thanks so much for your help.

    I am getting the formula to work somewhat. when I test it, I am getting incorrect results. I have tested the formula so far by:

    • Removing a date in the 'Date of Birth' to see if it returns the 'null' condition, "Missing D.O.B." which it does not.
    • There also seems to be something wrong with the age range '0-11' as it returns records that are over 11 years of age.


    Any suggestions on how to fix? If making the field return just a '1' if the record is within the age range or a null or 0 if the record is in the age range is easier, that would be great as I need to just count those records in each age range anyhow.

    Forgot to give you the formula I used in the 0-11 age range field:


    var date DOB = [Date of Birth];
    var number AGE =
    Year(Today())-Year($DOB)
    -
    If(Month(Today())<Month($DOB)
    or
    (Month(Today())=Month($DOB) and Day(Today())<Day($DOB)),1,0);
    If(IsNull($DOB), "Missing D.O.B.",$AGE <=11, "0-11")

    I'm not understanding why you would want to have separate fields for each date range result. It should just be one field.

    When I get a chance tonight I will replicate the formula and test it, but it sure looks right to me.
    I have attached a jpg of the data requested in a monthly report that segregates the age categories needed for reporting. Maybe I am approaching this problem the wrong way??? Should this be done through the QB reports process?
    OK, I f you want to easily create a report to look like that, yes I see why you would want to have separate fields.  You would want that to be a numeric formula field to calculate to a 1 or a 0.

    var date DOB = [Date of Birth];

    var number AGE =
    Year(Today())-Year($DOB)
    -
    If(Month(Today())<Month($DOB)
    or
    (Month(Today())=Month($DOB) and Day(Today())<Day($DOB)),1,0);

    If(IsNull($DOB), 0, $AGE <=11, 1,0)


    I did test the formula I originally posted and it worked for me.  Contact me via the information in my profile if you would like some one on one assistance.
    I think I am getting it. Just a question on the ranges; For the next age range, '12-15' is the last formula this:     If(IsNull($DOB), 0, $AGE >11<=15, 1,0)
    You were close

    If(IsNull($DOB), 0,
    $AGE >11 and $AGE<=15, 1,0)
    Thanks. I have added the fields based on each age category and tested it with various DOB's. It looks good. It's working! Thanks so much for your help. I am not sure I would have been able to get this one on my own.
    Great to hear.  It gets easier the more you play with the product!
