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).

Use $( )

Code:
val=$( echo $( echo $( echo "abc" ) ) )
echo $val
abc

Here are some reasons why is $(...) preferred over `...` (backticks)?
