I have used the following statement, but it is returning an incorrect result
for some cells. In an cell containing an age of 10 years, 11months..the
formula is returning "6m-2y" when it should say older than 2. It also does
this for the age 25 years 6 months and 18 years 10 months. Please help.

=IF(AND(E203="0years,0months",E203<="0years,3mont hs"),"0-3",IF(AND(E203"0years,3months",E203<="0years,6mon ths"),"3-6",IF(AND(E203"0years,6months",E203<="2years,0mon ths"),"6m
- 2y",IF(AND(E203"2years,0months",E203<="99years,0m onths"),"Older than
2",""))))
