• From , drag Call Parameters Into Variable to the bottom of the program. No indenting!
• Change my_var to encrypted_message and change my_function to encrypt.
• Change my_parameter1 to message and change my_parameter2 to key.

When the function is completed, it will store our secret message in the encrypted_message variable!
