List of People - Age Field

[waldonj 0]

Can someone clarify the use of the Age field in a filtered group for List of people. I am trying to make report queries simpler for me. For example in order to query the likely people to have World War I Registration Cards, I create a filtered group with Birth > a specific year, then Birth < another specific year, and Sex = M to locate likely candidates. It would be simpler if I could just query men whose Age was 18 to 45 in the year 1918, but I cannot figure out how to specify that using the Age field.
