Thank you for the help! Working script as follows:

Code:

#!/bin/bash
# Set count to zero to track amount of guesses
# Set win=no for while loop condition
win=0
count=0
echo "What is your name?"
read name
echo "Hello, $name, welcome to the Grand Random Number Enumerator Guessing Game!"
echo "Please pick a number that will be the highest number in the game"
read number
while [[ $number != +([0-9]) ]]; do
	if [[ $number == ([[:alnum:]]) ]]; then
		echo "Please input a number"
		read number
	elif [[ $number == +([['!@#'$'%^&*()-=+']]) ]]; then
		echo "Please input a number"
		read number
	elif [[ $number == +([[:alpha:]]) ]]; then
		echo "Please put in a number"
		read number
	elif [ -z $number ]; then
		echo "Please enter a number"
		read number
	fi
done
secret=$(($RANDOM % $number + 1))
echo "You have chosen $number"
echo "I have picked a number between 1 and number"
echo "Try and guess my number!"
read guess
while [ $win = no ]; do
	if [ -z $guess ] || [[ $guess == +([[:alpha:]]) ]] || [[ $guess != +([[:digit:]]) ]] || [[ $guess == +(['!@#$%^*()_+]) ]]; then
		echo "Please enter a number"
		win=no
		read guess
	elif [ "$guess" -lt "$secret" ]; then
		echo "Higher, Please guess again"
		win=no
		count=$((count + 1))
		read guess
	elif [ "$guess" -gt "$secret" ]; then
		echo "Lower, please guess again"
		win=no
		count=$((count + 1))
		read guess
	elif [ "$guess" -eq "$secret" ]; then
		echo "WINNAH! YOU AHH WICKED SMAHT!"
		echo "It took you $count tries to guess my number"
		win=yes
	fi
done
echo "Would you like to play again?, <yes/no>"
read answer
checkagain=yes
while [ $checkagain = yes ]; do
	if [[ $answer == [Yy][Ee][Ss] ]]; then	
		exec /***/***/guessingame.sh
		checkagain=no
	elif [[ $answer == [Nn][Oo] ]]; then
		checkagain=no
		echo "YOU'RE FIRED!!!!"
		exit 0
	elif [[ $answer != ^[Yy][Ee][Ss]$ ]] || [[ $answer != ^[Nn][Oo]$ ]]; then
		checkagain=yes
		echo "Please input either "yes" or "no"
		read answer
	fi
done

qmail-pw2u

qmail-pw2u(8)						      System Manager's Manual						     qmail-pw2u(8)

NAME

       qmail-pw2u - build address assignments from a passwd file

SYNOPSIS

       qmail-pw2u [ -/ohHuUC ] [ -cchar ]

DESCRIPTION

       qmail-pw2u reads a V7-format passwd file from standard input and prints a qmail-users-format assignment file.

       A V7-format passwd file is a series of lines.  Each line has the format

	  user:password:uid:gid:gecos:home:shell

       where  user  is an account name, uid and gid are the user id and group id of that account, and home is the account's home directory.  pass-
       word, gecos, and shell are ignored by qmail-pw2u.

       If you put the output of qmail-pw2u into /var/lib/qmail/users/assign, and then run  qmail-newu,	qmail-lspawn  will  obey  the  assignments
       printed by qmail-pw2u.  WARNING: After changing any users, uids, gids, or home directories in your passwd file, you must run qmail-pw2u and
       qmail-newu again if you want qmail-lspawn to see the changes.

RULES

       By default, qmail-pw2u follows the same rules as qmail-getpw.  It skips user if (1) uid is zero, (2) home does not exist, (3) user does not
       own  home, or (4) user contains uppercase letters.  It then gives each remaining user control over the basic user address and all addresses
       of the form user-anything.  A catch-all user, alias, controls all other addresses.

       You may change these rules by setting up files in /var/lib/qmail/users:

       include
	      Allowed users, one per line.  If include exists, and user is not listed in include, user is ignored.

       exclude
	      Ignored users, one per line.  If exclude exists, and user is listed in exclude, user is ignored.

       mailnames
	      Replacement names for users.  Each line has the form

		 user:mailname1:mailname2:...

	      The addresses mailname1 and mailname1-ext and mailname2 and so on will be delivered to user.

	      WARNING: The addresses user and user-ext will not be delivered to user unless user is listed as one of the mailnames.

	      A line in mailnames is silently ignored if the user does not exist.

       subusers
	      Extra addresses.	Each line has the form

		 sub:user:pre:

	      sub will be handled by home/.qmail-pre, where home is user's home directory; sub-ext will be handled by home/.qmail-pre-ext.

       append Extra assignments, printed at the end of qmail-pw2u's output.

OPTIONS

       -o     (Default.)  Skip user if home does not exist (or is not visible to qmail-pw2u).  Skip user if home is not owned by user.

       -h     Stop if home does not exist.  This is appropriate if every user is supposed to have a home directory.  Skip  user  if  home  is  not
	      owned by user.

       -H     Do not check the existence or ownership of home.

       -U     (Default.)  Skip user if there are any uppercase letters in user.

       -u     Allow uppercase letters in user.

       -cchar Use char as the user-extension delimiter in place of -.

       -C     Disable the user-extension mechanism.

       -/     Use home/.qmail-/...  instead of home/.qmail-...
