I pulled a rabbit outa ma hat. I hope we didn't step on each other. Given
typeset -i selection and typeset chselection
I assign chselection to selection. If chselection is nonnumeric then 
selection gets set to zero. Then

if (( selection == 0 )) && [[ "$chselection" != 0 ]]
then
    echo 'Error: Input must be numeric'
elif (( selection >= 0 && selection < size )) 
then
    eval ${action[selection]}       # Do it baby.
else
    # Bitch if the input was out of bounds.
    echo 'Error: Input must be in range'
    nogood=1
