Nesting backticks
I'm trying to make a dialog window that prints the output of grep that takes the output of find. Unfortunately my nested backticks don't work.

Here is the dialog window:

Code:
dialog --stdout --title "test" --backtitle "test" --msgbox "Test:\n `grep -l "${tablica[5]}" `find $string``" 16 60

I think I understand why it doesn't work (multiple ways on how to interpret the backticks), but I have no idea how to go around it.

Basically I'm making a basic window that prints all files that meet "find" search criteria and contain certain word inside (thats' what I use grep for).

tk_dialog(n)						       Tk Built-In Commands						      tk_dialog(n)

__________________________________________________________________________________________________________________________________________________

NAME

       tk_dialog - Create modal dialog and wait for response

SYNOPSIS

       tk_dialog window title text bitmap default string string ...
_________________________________________________________________

DESCRIPTION

       This procedure is part of the Tk script library.  Its arguments describe a dialog box:

       window Name of top-level window to use for dialog.  Any existing window by this name is destroyed.

       title  Text to appear in the window manager's title bar for the dialog.

       text   Message to appear in the top portion of the dialog box.

       bitmap If  non-empty,  specifies a bitmap to display in the top portion of the dialog, to the left of the text.	If this is an empty string
	      then no bitmap is displayed in the dialog.

       default
	      If this is an integer greater than or equal to zero, then it gives the index of the button that is to be the default button for  the
	      dialog (0 for the leftmost button, and so on).  If less than zero or an empty string then there will not be any default button.

       string There  will  be  one  button  for each of these arguments.  Each string specifies text to display in a button, in order from left to
	      right.

       After creating a dialog box, tk_dialog waits for the user to select one of the buttons either by clicking on the button with the  mouse	or
       by  typing  return  to invoke the default button (if any).  Then it returns the index of the selected button:  0 for the leftmost button, 1
       for the button next to it, and so on.  If the dialog's window is destroyed before the user selects one of the buttons, then -1 is returned.

       While waiting for the user to respond, tk_dialog sets a local grab.  This prevents the user from interacting with the  application  in  any
       way except to invoke the dialog box.

EXAMPLE

	      set reply [tk_dialog .foo "The Title" "Do you want to say yes?" 
		      questhead 0 Yes No "I'm not sure"]
