keeping count

globals.js
var g_square_id=0;
var g_letters=0;
var g_found=0;

load_squares.js
        el.textContent='_';
        g_letters++;

key_clicked(el) in clicks.js

And this will also be where we want to move on to the next square to be filled in.

    square.style.color='black';
    g_found++;
    move_on(g_square_id);

The move_on function is probably the trickiest code for the project - please study the next page very carefully.
