Filename to Filename OK button dimmed?

e.g.

Old Filename

%artist% - %album% - $num(%track%,2) - %title%

New Filename

%artist% - %album% $num(%track%,2) %title%

Preview and OK are dimmed. Is it possible it is looking at the filename and doesn't see how it could conform to the old filename pattern I am using?

Can I get an explanation of the syntax

$num(%track%,2)

Are there some examples someplace?

That's not how you use scripting in this converter.  
You use %1, %2, %3, ... to match the filename  
I guess for your filename you could use  
old:  
%1 - %2 - %3 - %4  
new:  
%1 - %2 %3 %4

Ahhh, I think I get it. This convertor basically RE-ARRANGES or RE-ORDERS existing pieces of the existing filename, like changes 1 2 3 4 to 1 4 2 3 or something. Will give it a try.
