different data attribute

[Shashi Gireddy]

HI,
I have all alabama state related shp/dbf/shx files with me, i want  to
add another attribute to my dbf file (ex. I had FIPS,NAME,POP_2000
in my dbf file and now i want to add No_of_accidents to it.) Initially
i tried adding a seperate column  using excel but that didn't work.
Can anybody help me?.

Is it possible to show a different query/map if the user clicks on a
perticulor place of the map?

thank you,
shashi.
