Hi
I am using 2 option menus in a program.
One menu gets it's variables from a unix "ls" command and
the other menu should be updated according to the
selected directory in the first option menu.
I used the following code, but it doesn't seem to work: 
$mw->Label(-text=>"level1 ")->grid(
      $mw->Optionmenu(-textvariable=>\$selectedDir,
           -command=>
     sub{ @files=`ls $path/$selectedDir`;       
             foreach (@files) {chomp();} },
               -options=>\@myArr),

      $mw->Label(-text=>"level2 "),
      $mw->Optionmenu(-textvariable=>\$myFile,
                  -options=>\@files)
                                  );

When the window is displayed, the second option box is empty,
and when i try to select something from it, i get an error.
I tried giving the $files[0] a value, but it still wasn't
updated after selecting a different option on the first option menu.
I am using Tk and this is not a web-based program.
Could someone please help ? Thanks
