Question : Another interesting excel - add concatenate to vlookup

Hi All,
I have unique problem with vlookup this time. I am trying to add concatenate function in vlookup so that result brings me back the result of concatenate and its refrence number.

Here is the question:

I have 2 tabs in excel, and the first tab looks like this
Full_Name        Age
Johnny Ola       16
Marlon Ho         24
Kim Sum           25

I need to fill Age column shown above from tab 2 below which looks like:

First_Name   Last_Name    Age
Johnny               Ola            16
Marlon                 Ho            24
Kim                      Sum         25

-------------
So the question I want to repeat is that I am trying to do vlookup in first tab in 'Age' column which looks up full name in second tab which is split like Firs_ Name, Last_Name and Age.
I know I can add extra column in tab 2 and concatenate the first and last name and then do the vlookup. But thats not how I want to do.
I hope I am clear.
Any help or suggestion will be really apreciated.

Can you post a sample just censoring the actual names so I can see what exact formula you are using and where?
