How do I SCP from remote machine to local machine?

I know there are some similar questions has been asked here and I did read them... however, I still can not copy a file from a remote machine down to my local computer... I am keep getting error like "No such file or directory"

Here is what I do. I open terminal on MacOS, log in to the remote machine, cd to the folder I want. Now, under this folder I have a .txt file, say "error.txt", and I want to copy this file down to my local desktop.

I get the directory for my local desktop by just drag the desktop folder into the terminal and I got a path /Users/myname/Desktop

Then I tried the following commands (while under the folder the error.txt is inside the remote machine):

scp -r error.txt /Users/myname/Desktop

or some variations

scp -r error.txt :/Users/myname/Desktopscp -r error.txt ~/Users/myname/Desktopscp -r error.txt Users/myname/Desktop

but all of them are keep giving me the error like

cannot create regular file `/Users/myname/Desktop': No such file or directory

Maybe my trouble is how to correct write my local path? But I can cd to my local desktop by using the path /Users/muname/Desktop while inside my local machine...

Any helps?Thank you!
