You need to find out how the second whiptail writes its output. Somehow the output of the second whiptail command needs to be fed into the while-read loop. There is not input into that loop here. Perhaps through a pipe symbol (if that command outputs on stdout)?

--
A short look at the man page of whiptail and the menu option, says it's outputting on stderr. But it also needs stdout to go to the terminal, so a pipe cannot be used)

===EDIT===
(corrected previous sentence (thanks Don). I originally said "background" there, which is wrong I meant "subshell". But also that is not really relevant. What matters is that pipe cannot be used like that, because the command needs stdout to go directly to the terminal..)

So try something like:

Code:
.....
whiptail --title Networking --menu "Make your choice" 16 78 5 \
  "1)" "Display info" 2>somefile
CHOICE=$(cat somefile)
case $CHOICE in
  "1)") ./displayinfo.sh
esac

set_color

set_color(1)							       fish							      set_color(1)

NAME

       set_color - set_color - set the terminal color

set_color - set the terminal color
   Synopsis
       set_color [-v --version] [-h --help] [-b --background COLOR] [COLOR]

   Description
       Change the foreground and/or background color of the terminal. COLOR is one of black, red, green, brown, yellow, blue, magenta, purple,
       cyan, white and normal.

       o -b, --background Set the background color

       o -c, --print-colors Prints a list of all valid color names

       o -h, --help Display help message and exit

       o -o, --bold Set bold or extra bright mode

       o -u, --underline Set underlined mode

       o -v, --version Display version and exit

       Calling set_color normal will set the terminal color to whatever is the default color of the terminal.

       Some terminals use the --bold escape sequence to switch to a brighter color set. On such terminals, set_color white will result in a grey
       font color, while set_color --bold white will result in a white font color.

       Not all terminal emulators support all these features. This is not a bug in set_color but a missing feature in the terminal emulator.

       set_color uses the terminfo database to look up how to change terminal colors on whatever terminal is in use. Some systems have old and
       incomplete terminfo databases, and may lack color information for terminals that support it. Download and install the latest version of
       ncurses and recompile fish against it in order to fix this issue.
