the count wont update
your add method adds the selected item to second list box and increments the count variable.. But page level variables loose their value after postback roundtrip cause they are reinitialised every time your page loads.. so your count variable will always hold the value of 0 and when incremented, 1. This wont work...
Why not just use
to get the count of items in second listbox?
