what is an action that i can make, so that when i click on a file, and then it takes the album and makes it blank??

I attached an simple action, which you have to install in this folder:
%appdata%/Mp3tag/data/actions

Simply run the execute command under the start button of windos and type in that line above. There you have to copy the action, which you can then access with a right click in Mp3tag.
