Drawing mysteriously disappeared from the canvas

Having trouble with my JavaScript code. I created a function called drawLine to trace lines on a canvas from one point (x,y) to another point (xdest, ydest). The first few lines display correctly but after the fourth line, it stops working and I can't figure out why. Any ideas?

    var canvas2 = document.getElementById("canvasMid");
    var ctx = canvas2.getContext('2d');
    ctx.fillStyle = color;
    drawLine(ctx,(canvas.width/2),0,(canvas.width/2)-2,canvas.height,color,width);
    drawLine(ctx,canvas.width/2,(1/5)*canvas.height,0,0,color,width);
    drawLine(ctx,canvas.width/2,(1/6)*canvas.height,canvas.width,0,color,width);
    //start of the part that's not working
      drawLine(ctx,canvas.width/2,0.5*canvas.height,0,canvas.height,color,width);
      console.log(canvas.width,canvas.height)
      drawLine(ctx,canvas.width/2,(3/4)*canvas.height,canvas.width,canvas.height,color,width);
    //end 


}

function drawLine(ctx,x,y,xdest,ydest,color,width){
    ctx.beginPath();
    ctx.moveTo(x,y);
    ctx.lineTo(xdest,ydest);
    ctx.strokeStyle = color;
    ctx.lineWidth = width;
    ctx.stroke();
    ctx.closePath();
}

First line in the center; Second line on the left; Third line on the right
