EAC generating filenames

I've been using EAC with Lame for a while now. However, I still can't get the filenames to generate properly. I like "TrackNumber_TrackName.mp3" for the naming scheme but I can't get EAC to do this. I use MP3 Tag Studio to clean up the file names after ripping. But this extra step should be unnecessary and Tag Studio is using popup ads now.

I think I have EAC setup right, so what am I missing. Attached it a screen shot. Currently, EAC outputs "TrackName.mp3". I am using v0.90 prebeta 11. Thanks.

Try the filename options under EAC|EAC Options|Filename, rather than these ones.

That was it! Thanks!
