How to read user keyboard input inside the case?

I need to Write a shell script that allows some system-administration tasks to be preformed automatically from a menu-driven interface. with automated following tasks:

Copy directory tree
Delete files or directories
Output Information (this part is done )

*Copy directory tree
The �Copy directory tree� selection should prompt for two arguments: src & dest.
The script then copies all the files from src, including all the subdirectories, to dest,
creating all the necessary sub-directories.
The script must perform necessary argument validation, assuming that the first argument may be either a directory name or the name of a regular file, while the second may be only a directory name.

my problem with this assignment is I can not read user input inside the "case" options.
I think I need to ask user to enter src and dest for copying the files.

this is my code so far

Code:

#!/bin/sh
clear
	echo "\t `date "+%d/%m/%Y"`"
	echo "\t Hostname Machine: `hostname`"
	echo "\t user: `whoami` "
	echo "\t M A I N - M E N U"
	echo "\t 1.Copey Directory Tree"
	echo "\t 2.Delete Files or Directories"
	echo "\t 3.Output Information"
while true ; do
	echo -n "\t Please enter an option [ 1 - 4 ] : "
	read opt

	case "$opt" in
		1) echo "Enter the source and destination for copying files" ;; 
		
		#read src dest ;;
		#echo "$src" ;;
		#echo "$dest" ;;

		2)  ;;

		3) echo "\t the number of possible users on the system: `cat /etc/passwd |wc -l` \n\t the number of current user on the system : `who | wc -l`\n\t the number of processes running: `ps -e | wc -l`"  ;;


		*) exit ;; 
	esac
done
