increase an array value

thanks. my other question is...
i have a list box that is populated via DAT file which is loaded into the array..

20 rows
3 columns
________________
MyArray
________________
1, Gabe Matteson, N
2, J Matteson, N
3, P Matteson, N
4, A Matteson, N

________________
list box
________________
1, Gabe Matteson, N (listindex 0)
2, J Matteson, N (listindex 1)
3, P Matteson, N (listindex 2)
4, A Matteson, N (listindex 3)

now my question is, i can remove the items in the lsit box by the listindex.. so if i remove Gabe Matteson from the listbox, the next name "J Matteson" recieves the index value of 0. so when i type in 2 because "2, j matteson, n" to delete that name, it wont because the list index is 0...does anyone know how to fix this? thanks,
