using flags Using command-line parameters as destination atribute for cp and mv in bash script

I am attempting to do copy a file (or rename a file) by running the script with flags/parameters to give both the source and the destination file name:

#!/bin/bash/

while getopts s:d flag
do
        case "${flag}" in
                s) copy_source=${OPTARG};;
                d) copy_dest=${OPTARG};;
        esac
done

echo "Copy a file input with argument to another file input with argument"
cp $copy_source $copy_dest

The output is an error:

sh test_cp.sh -s  file1.txt -d file2.txt
Copy a file input with argument to another file input with argument
cp: missing destination file operand after ‘file1.txt’
Try 'cp --help' for more information.

Does cpcp (and mvmv) not accept parametrized destination  ? What am I doing wrong  ?
