Why won't I be prompted for input
 

Help!

I am trying to write some PL/SQL code to display a menu and get prompted for me to enter a selection. I've created 2 procedures and am trying to call those 2 procedure from a PL/SQL block. When I create the selection procedure using variable substitution, I get prompted for input. But when I call the procedure from within a PL/SQL block, I don't get prompted. Is it possible to call the procedure and get prompted to enter a selection.

Please take a look at my two procedures and main pl/sql block that is attached and give me some hints or pointers as to what I am doing wrong.

Thanks for any assistance.
