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
