Data main program is not calling small other programs

I am trying to understand a program in a book and this program suppose to call other programs which are in the same folder, the other programs are called 'lu' and 'add' but for some reason when it gets to the last line of each case to call these programs there is an error message saying
Code:
./rolo: line 29: lu: command not found  OR  
./rolo: line 29: add: command not found

and the lu program looks like this:
Code:
#!/bin/bash
#
# Look someone up in the phone book
#

grep "$1" phonebook

echo '
     would you like to:

            1. Look someone up
       2. Add someone to the phone book
       3. Remove someone from the phone book

       Please select one of the above (1 - 3): \c'

#
# Read and process selection
#

read choice
echo
case "$choice"
in
    1) echo "Enter name to look up: \c"
       read name
       lu "$name";;
    2) echo "Enter name to be added: \c"
       read name
       echo "Enter number: \c"
       read number
       add "$name" "$number";;
    *) echo "Bad choice";;
esac

I don't understand why is not calling them. Please any help is appreciated. Thank you.

NAME
echo - echo arguments to standard output SYNOPSIS
/usr/ucb/echo [-n] [argument] DESCRIPTION
echo writes its arguments, separated by BLANKs and terminated by a NEWLINE, to the standard output. echo is useful for producing diagnostics in command files and for sending known data into a pipe, and for displaying the contents of envi- ronment variables. For example, you can use echo to determine how many subdirectories below the root directory (/) is your current directory, as follows: o echo your current-working-directory's full pathname o pipe the output through tr to translate the path's embedded slash-characters into space-characters o pipe that output through wc -w for a count of the names in your path. example% /usr/bin/echo "echo $PWD | tr '/' ' ' | wc -w" See tr(1) and wc(1) for their functionality. The shells csh(1), ksh(1), and sh(1), each have an echo built-in command, which, by default, will have precedence, and will be invoked if the user calls echo without a full pathname. /usr/ucb/echo and csh's echo() have an -n option, but do not understand back-slashed escape characters. sh's echo(), ksh's echo(), and /usr/bin/echo, on the other hand, understand the black-slashed escape characters, and ksh's echo() also understands a as the audible bell character; however, these commands do not have an -n option. OPTIONS
-n Do not add the NEWLINE to the output. ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWscpu | +-----------------------------+-----------------------------+ SEE ALSO

The -n option is a transition aid for BSD applications, and may not be supported in future releases. SunOS 5.11 3 Aug 1994 echo(1B)
