The bang takes two arguments - you have to tell it the name of the evar you're 
saving, and then what you want the evar to be. So the following would save the 
full path to a color scheme file in the evar "colorscheme":

*Popup "Select color scheme" !new !popupSchemes
   *Popup "Select color scheme"	!popupDynamicACtionFolder:!savesetting 
colorscheme:"$SchemesDir$"
*Popup ~New

If you want just the "name" of the scheme, then you have to be a little fancier, 
since the full path just gets tacked on at the end of the popup dynamic action 
bang. Instead I define the popup action to be !savescheme:

*Popup "Select color scheme" !new !popupSchemes
   *Popup "Select color scheme"	!popupDynamicACtionFolder:!savescheme:"$SchemesDir$"
*Popup ~New

...and then define !savescheme to do the saving and stripping, where the %1 is 
the full path that is passed in from the popup:

  *alias !savescheme !execute [!saveSetting colorscheme %1][!strippath 
colorscheme][!stripextn colorscheme]

Try it both ways and look at the results - you'll get the picture. =)
