Creating a .layout file with two command arguments

[Jeremy Daily]

Group,

I'm trying to make a .layout file for sae.cls. I have everything working 
except the authors. In the sae class, the authors are added using the 
command:

\AddAuthor{Author name}{Affiliation}

If I try:

Style Author
Margin        Static
LatexType        Command
InTitle        1
LatexName        AddAuthor
End

in the LyX .layout file, an error is given. I cannot figure out a way to 
include two two values for one command in LyX. My alternative right now 
is to use \AddAuthor in the document preamble, which seems to work fine.

Any help is much appreciated.
