How to display choices in alert message using javascript

Hi,

I have three list boxes on my form say Cate1, Cate2 and Cate3.
as each having same choices or option and value as below.
choices value
A 1
B 2
C 3
D 4
. .
. .
X 35
Y 36
Z 37


Suppose user selected A,B,C as their categories while registration time. When user comes to edit page. He will be displayed these 3 categories.

When he change category B to X then alert has to populate saying that " You have changed your old category B to Y "
not like this " You have changed your old category 2 to 36"

Can we do this ? pls provide me the solution for this asap.

Regards
