Move or Rename Files and Directories with mv

Question

I've tried using:

mv filename destination path

Unfortunately, I am faced with an error message:

mv filename destination_path
mv: cannot stat 'filename': No such file or directory

How to I get this desired output?

mv path_to_file/filename destination_path    
input: mv filename destination_path
Output: mv: cannot stat 'filename': No such file or directory
