How to generate a LIST from codes

Hi, I work on Excel 2003 and XP-SP2 operating system. I have approx 26 error types (say from A-Z), like :
Code------- Description
A ----------- No address
B ----------- No account
C ----------- No name, etc etc.

I would like to input the error code in a cell, and get the description in the adjoining cell, one beneath the other. E.g. if I type only C in cell A1, then the output in cell B1 should be No Name.

However, if I type ABC in cell A2, then output in cell B2 should look like :
No address
No account
No name

I checked lots of posts but could not find the answer, so if anyone can help me with this, I will be very grateful. thanks in advance....b
