When I try to add a sound to my level in WED all's it says is empty.

Hmm - maybe you could tell a little more detailed what your problem is. Or just try recording a sound that says: "It's full".

When I tried to add a sound through Wed (Version 7.82) by ether right clicking on the screen then going add sound or by going to objects: add sound, when I try clicking on that add sound button it does nothing it just says empty. Sounds and music do work, I can easily add it with coading,but it’s just when I add it through Wed where it doesn’t work.

Is this better?

Not really. Gamestudio comes with many sound files, but like all other files, only the files in your project folder or path belong to the project.

What sound files do you have in your project folder?

Sorry for the confusion.
I got it to work, It has to be a .wav file, I thought it could be a .mp3 file to. Guess I'll just add it with SED. Thanks for the help.
