Thanks for the suggestion. I was not able to implement your suggestion into my coding. It may be due to the way I have my code set up. Here is the function I created:
Code:
function yesSelected()
{
local word=$(randomWord)
local count=0
local countChar=0
local correctWord="n"
local chars
local attempts=10
local display
local charLower




        clear
        while [[ $correctWord = "n" && $count -lt $attempts ]]
        do
        echo $word
        gameDisplay $count $countChar $display $chars
        echo
        read -p "Please enter a character: " char
        charLower=$(echo "$char" | tr [A-Z] [a-z] )
        (( countChar=countChar + 1 ))
        if [[ "$(letterValid $charLower)" -eq 0 ]]
        then
          if [[ $chars =~ .*$charLower.* ]]
          then
          clear
          charUsed
          else
            chars="${chars}${charLower}"
            if [[ $word =~ .*$charLower.* ]]
            then
                ((count = count))
              else
                ((count = count + 1))
            fi
              display=$(echo "$word" | sed "s/[^${chars}]/-/g")
            clear
            if [ $word = $display ]
            then
              correctWord="y"
              clear
            fi
          fi
        else
          clear
          invalidErrorMessage
        fi
        done
        if [[ $count -eq 10  ]]
        then
          echo "SORRY. The word was $word."
          echo
          tooManyAttempts
          echo
          gameEnded
          else
                congratsScreen
                gameEnded
          fi
}

yesSelected

I pass in a "randomWord" from another function and then use it to perform the task. I am trying not to use SED in my program so I wanted to see if there is another way to get the same result.

Thanks again for your help in this matter.

tping

TPING(1)							   LAM COMMANDS 							  TPING(1)

NAME

       tping - Send echo messages to LAM nodes.

SYNOPSIS

       tping [-hv] [-c count] [-d delay] [-l length] nodes

OPTIONS

       -h	     Print the command help menu.

       -v	     Turn OFF verbose mode.

       -c count      Send count messages.

       -d delay      Delay delay seconds between each message.

       -l length     Each message is length bytes long.

DESCRIPTION

       The  tping  command  sends  messages  to,  and  collects replies from, a list of nodes, via the LAM echo server.  It is similar to the UNIX
       ping(8) command, and is used as a quick diagnosis of the LAM network.

       Unless options are specified, tping sends a 1 byte message an infinite number of times, displaying the roundtrip time of each message as it
       completes,  with  a delay of 1 second between roundtrips.  After the loop is broken (with keyboard interrupt, eg: ^C), tping prints statis-
       tics about all roundtrip messages.

EXAMPLES

       tping h
	   Echo messages to the local node.

       tping -v n7 -l 1000 -c 10
	   Echo 1000 byte messages to node 7.  Stay silent while working.  Stop after 10 roundtrips and report statistics.

BUGS

       There is no built-in timeout and tping will wait forever to receive an echo.  If no echo is received, due to a dead  link  or  node,  tping
       hangs.	Stop  the  process  with  a  keyboard suspend signal (eg: ^Z) and terminate LAM with lamhalt(1) or lamwipe(1) (although the use of
       lamwipe(1) is deprecated).

       lamhalt(1), lamwipe(1)
