Hi,
You need to leave the command name as a string reserved for the command name that you would like to call to use what has written in the macro section, so just add the following into the macro section:
Code:
^C^C(setvar "cmleaderstyle" "Proposed") _mleader
Note:
1- You need to be sure is that the Mleader style name is available into your current drawing otherwise an error would occur.
2-Note that there is a space before the Mleader command.
The name of the command and as shown in the attached image is: Test and you can rename as per your needs.
