IF loop syntax error
I am trying to run a menu option though IF loops. I keep getting errors not allowed the menu to be processed correctly. Currently it will accept the first 2 statements but then crash on the 3rd. The 2nd and 3rd have the same syntax, so I do not understand why it breaks.

Code:
#!/bin/bash

while true; do

    read -p "Enter project number (1/2/3/10/20/30):"
    $menu
    
    if [ $menu -eq 1 ]; then
    {    
    echo "1"
    }
    elif [ $menu -eq 2 ]; then
    {
    echo "2"
    {
    elif [ $menu -eq 3 ]; then
    {
    echo "3"
    {
    elif [ "$menu" == "10" ]; then
    {
    echo "10"
    {
    elif [ "$menu" == "20" ]; then
    {
    echo "20"
    {
    elif [ "$menu" == "30" ]; then
    {
    echo "30"
    {    
    fi

read -p "Would you like to process another project? [y/n]" yn
case $yn in
    [Yy]* ) ;;
    [Nn]* ) exit;;
        * ) echo "Please select proper entry:";;
    esac
done

tk_popup(3tk)						       Tk Built-In Commands						     tk_popup(3tk)

__________________________________________________________________________________________________________________________________________________

NAME

       tk_popup - Post a popup menu

SYNOPSIS

       tk_popup menu x y ?entry?
_________________________________________________________________

DESCRIPTION

       This procedure posts a menu at a given position on the screen and configures Tk so that the menu and its cascaded children can be traversed
       with the mouse or the keyboard.	Menu is the name of a menu widget and x and y are the root coordinates at which to display the	menu.	If
       entry  is omitted or an empty string, the menu's upper left corner is positioned at the given point.  Otherwise entry gives the index of an
       entry in menu and the menu will be positioned so that the entry is positioned over the given point.

EXAMPLE

       How to attach a simple popup menu to a widget.
	      # Create a menu
	      set m [menu .popupMenu]
	      $m add command -label "Example 1" -command bell
	      $m add command -label "Example 2" -command bell

	      # Create something to attach it to
	      pack [label .l -text "Click me!"]

	      # Arrange for the menu to pop up when the label is clicked
	      bind .l <1> {tk_popup .popupMenu %X %Y}
