Custom Post Type will not execute shortcode

Hi there,

I have created a Custom Post Type. One of the fields in the CPT holds a Revolution Slider shortcode e.g. [rev_slider test1]. So each page of the CPT therefore has a different slider.

I want to be able to call this shortcode into the template. Calling it directly does not work as it only retrieves the shortcode and does not execute it e.g.

$testslider1= get_field('rev_slider',$post->ID);
	if( $testslider1{
	echo '<div class="test1-slider"> '.$testslider1.'</div>';
}

I have also tried executing the shortcode directly, it does not appear to be able to pull in CPT content:

echo do_shortcode(‘.rev_slider.’);

Any ideas? Thanks…
