Bash if statement with multiple conditions throws an error

Question

I\'m trying to write a script that will check two error flags, and in case one flag (or both) are changed it\'ll echo-- error happened. My script:

my_error_f

if [ -z "$MYSQL_ROOT_PASSWORD" -a -z "$MYSQL_ALLOW_EMPTY_PASSWORD" -a -z "$MYSQL_RANDOM_ROOT_PASSWORD" ]; then
