I don't know what you mean by "the script is still running".

the "*" clause will match "N".

Not according to the script you posted....

Code:
echo "\nAre you sure you entered the right Destination Environment? y[n] : \c \n"

Nothing about case "N", nothing about "valid number". Your case statement is just plain wrong.
