Looking up data in a database

I have a database in excel and then a vlookup formula in another page looking up all a members details.
So I have year joined and date of birth
So I need a formula that members that have been with us for 25 years should say honorary
members who are under 18 years of age should say junior.
Members who are dont fit into any of these should say full

You get better help, if you post an excel file, without confidentional information.

Please also add, the desired result.

A1: Year Joined
B1: DOB

C1: =IF(DATEDIF(A1, TODAY(), "y")>=25, "honorary", IF(DATEDIF(B1, TODAY(), "y")<18, "junior", "full"))

Two things:

- Read the forum rules regarding Topic Titles. Your title needs to be more descriptive
- You most likely need to include sample data to get better help

As far a general ideas toward a solution:
- Assuming you have three fields in columns (Name, Date_Joined and Date of Birth(DOB))
- Case 1: Junior Member =(TODAY()-DOB)/365 = Age in years. If Age <18 = Junior Member
- Case 2: Honorary =(TODAY()-Date_Joined)/365 = Year Joined. If Years_Joined >25 = Honorary
- Case 3: If not Case 1 or Case 2 = Full
