You could do several levels, in fact, I learned from Cetin


New method called :: GetAge

LPARAMETER ldDOB, llsex
age = (date() - ldDOB)/365.25

DO CASE
CASE age >= 0 and age < 12
 nColor = iif(llsex=0,RGB(0,0,0),RGB(0,0,100))
CASE age >= 12 and age < 18
 nColor = iif(llsex=0,RGB(100,0,0),RGB(100,0,100))
CASE age >= 18 and age < 30
 nColor = iif(llsex=0,RGB(200,0,0),RGB(200,0,100))
CASE age >= 30 and age < 60
 nColor = iif(llsex=0,RGB(0,100,0),RGB(0,100,100))
CASE age >= 60 
 nColor = iif(llsex=0,RGB(0,200,0),RGB(0,200,100))
ENDCASE

Return nColor

In Grid's Init

ogrd.SetAll("DynamicBackColor", "thisform.getAge(client.age,client.sex)", "Column")

Of course, you can set the display options as you like, e.g. you can display ICONs, instead of changing the fontcolor
