While loop not painting new lines with love.graphics.line

This piece of code should make a huge grid. I'm trying to make the code efficient so I obviously don't have to keep making lines to form a large grid.

    -- Grid Vertical
    local gx = 0 
    -- Grid Horizontal
    local gy = 0
    -- Grid Loop
    local g = 0
    while g ~= 100 do
        print("Grid Loop: "..g) -- for testing purposes of the loop
        love.graphics.line( gx, 0, gx, 500)
        love.graphics.setColor( 255, 255, 255 )
        love.graphics.line( 0, gy, 1000, gy)
        love.graphics.setColor( 255, 255, 255)
        local gx=gx+50
        local gy=gy+50
        g=g+1
    end
    end

When the program loads it only makes 2 lines at the very top of the GUI. The lines are barely visible but I managed to locate them when changed the line colour to red.

The finished GUI was completely black but I want my screen to look something like this: http://i.gyazo.com/7913c29776ba2248c07e37f3be9b64a4.png

remove those local behind gx and gy:

-- Grid Vertical
local gx = 0 
-- Grid Horizontal
local gy = 0
-- Grid Loop
local g = 0
while g ~= 100 do
    print("Grid Loop: "..g) -- for testing purposes of the loop
    love.graphics.line( gx, 0, gx, 500)
    love.graphics.setColor( 255, 255, 255 )
    love.graphics.line( 0, gy, 1000, gy)
    love.graphics.setColor( 255, 255, 255)
    gx=gx+50 -- ** there's no need for local
    gy=gy+50 -- ** you have these values before WHILE Loop.
    g=g+1
end
end
