creatinstallmedia for Mac oS Catalina not working, Why?

Hello, this is Stephen. I'm trying to use createinstallmedia to create a Mac oS Catalina install drive, but when I try I get the error, the volume could not be found. I made sure I was typing the name of the volume in Terminal correctly, which was Untitled, but I typed it exactly like that. I even tried dragging and dropping the Mac oS installer and the volume in terminal, but still the same error. Also, this is a fresh copy of the Mac oS installer, so I know it's a good copy. Any help would be greatly appreciated. Thanks in advance. Mac oS Catalina 10.15.3.
