		$captcha = Simplecaptcha::captcha($options);
		return View::make("form", array("captcha" => $captcha));

	});
	Route::post("process", function()
	{
		$rules =  array('captcha' => array('required', 'captcha'));
	    $validator = Validator::make(Input::all(), $rules);
	    if($validator->fails())
	    {

	    	echo "fails";

	    }else{

    <table>
        {{ Form::open(array('url' => 'process')) }}
        <tr>

	        </td>
	        <td>
	            {{ $captcha["img"] }}
	        </td>
        </tr>
        <tr>
            <td>
                {{ Form::label('captcha', 'Captcha') }}
            </td>
            <td>
                {{ Form::text('captcha') }}
            </td>
        </tr>
        <tr>
            <td>
            </td>
            <td>
                {{ Form::submit('Success') }}
            </td>
