Its still not working Smilie

Code:
function print_daemon_options {
    echo "Start Daemons - Please enter one or a combination of the following:"
    
    if isDatasubEnabled && isReconEnabled; then
        echo "1 = CGT, 2 = Subscriber, 3 = Order Monitor, 4 = Revaluations, 5 = Reconciliation, 6 = All, 7 = Exit"
        allowedInput="1 2 3 4 5 6 7"
    
    elif isDatasubEnabled && isReconEnabled=0; then
        echo "1 = CGT, 2 = Subscriber, 3 = Order Monitor, 4 = Revaluations, 6 = All, 7 = Exit"
        allowedInput="1 2 3 4 6 7"

    elif isDatasubEnabled=0 && isReconEnabled; then
        echo "1 = CGT, 3 = Order Monitor, 4 = Revaluations, 5 = Reconciliation, 6 = All, 7 = Exit"
        allowedInput="1 3 4 5 6 7"
        
    else
        echo "1 = CGT, 3 = Order Monitor, 4 = Revaluations, 6 = All, 7 = Exit"
        allowedInput="1 3 4 6 7"
    fi
    
    echo $(allowedInput)
}

function stop_daemons {
    print_daemon_options

    echo $(allowedInput)
}

All I want it to do is print the options and then echo the allowedInput numbers Smilie

Start Daemons - Please enter one or a combination of the following:
1 = CGT, 2 = Subscriber, 3 = Order Monitor, 4 = Revaluations, 5 = Reconciliation, 6 = All, 7 = Exit
print_daemon_options: ./wmfo_menu.sh[398]: allowedInput: not found

stop_daemons: ./wmfo_menu.sh[398]: allowedInput: not found

You seem to change things with each iteration you post. What you had originally seemed OK, except for the spaces in the variable declarations.

Code:
function print_daemon_options {
    echo "Start Daemons - Please enter one or a combination of the following:"
    
    if isDatasubEnabled && isReconEnabled; then
        echo "1 = CGT, 2 = Subscriber, 3 = Order Monitor, 4 = Revaluations, 5 = Reconciliation, 6 = All, 7 = Exit"
        allowedInput="1 2 3 4 5 6 7"
    
    elif isDatasubEnabled && isReconEnabled=0; then
        echo "1 = CGT, 2 = Subscriber, 3 = Order Monitor, 4 = Revaluations, 6 = All, 7 = Exit"
        allowedInput="1 2 3 4 6 7"

    elif isDatasubEnabled=0 && isReconEnabled; then
        echo "1 = CGT, 3 = Order Monitor, 4 = Revaluations, 5 = Reconciliation, 6 = All, 7 = Exit"
        allowedInput="1 3 4 5 6 7"
        
    else
        echo "1 = CGT, 3 = Order Monitor, 4 = Revaluations, 6 = All, 7 = Exit"
        allowedInput="1 3 4 6 7"
    fi
}

function stop_daemons {
    print_daemon_options

    echo $allowedInput
}


This is command substitution:

Code:
echo $(allowedInput)

meaning it will (try to) execute a program called "allowedInput" and return it's output to echo. That's why it gives you an error.

Thanks Scott. I have a further problem now.

Code:
# Validate users input when they start/stop daemons
function validateInput {
    input = "${$1}"
    allowedInput = "${2}"
    
    for allowedOption in ${allowedInput}
    do
        if [ ${input} -eq ${allowedOption} ]
        then
            return 0
        fi
    done
    
    return -1
}

function print_daemon_options {
    echo "Start Daemons - Please enter one or a combination of the following:"
    
    if isDatasubEnabled && isReconEnabled; then
        echo "1 = CGT, 2 = Subscriber, 3 = Order Monitor, 4 = Revaluations, 5 = Reconciliation, 6 = All, 7 = Exit"
        allowedInput="1 2 3 4 5 6 7"
    
    elif isDatasubEnabled && isReconEnabled=0; then
        echo "1 = CGT, 2 = Subscriber, 3 = Order Monitor, 4 = Revaluations, 6 = All, 7 = Exit"
        allowedInput="1 2 3 4 6 7"

    elif isDatasubEnabled=0 && isReconEnabled; then
        echo "1 = CGT, 3 = Order Monitor, 4 = Revaluations, 5 = Reconciliation, 6 = All, 7 = Exit"
        allowedInput="1 3 4 5 6 7"
        
    else
        echo "1 = CGT, 3 = Order Monitor, 4 = Revaluations, 6 = All, 7 = Exit"
        allowedInput="1 3 4 6 7"
    fi
}


function stop_daemons {

    print_daemon_options
    echo "$allowedInput"
    
    read daemonOption
    
    if [ "$daemonOption" = '7' ] ; then
           return
   
       else
       
           validateInput "$daemonOption" "$allowedInput"
           
           if [ ${?} -eq 0 ] ; then
               echo "good!"
           fi
    fi
}

It now echos the numbers that the user can enter. When I enter a number I get the error

validateInput: ./wmfo_menu.sh[427]: : bad substitution

any ideas guys?

You have spaces again, and an erroneous $ (not to mention lots of superfluous curly braces and quotes).
Code:
    input = "${$1}"
    allowedInput = "${2}"

Should be:

Code:
    input=$1
    allowedInput=$2

Interesting that your error is on line 427! Are you going to drip-feed us the whole script piece by piece?

Thanks Scott that worked. The line number it was erroring at was the last line in the file for some reason.
