[Plugin Issue] Text won't appear above shortcode…argh!

hi, have a nagging issue that i can’t solve. looked everywhere in the forum…i’ve seen this question asked, but no answer yet.

i’m using a plugin called “WPECARDS” that uses a shortcode. everything’s fine, EXCEPT i cannot get text i write in the post to appear ABOVE the shortcode. no matter what i do, the text always appears BELOW the shortcode generated content.

for example, if i write this in a post:
intro copy, intro copy, intro copy
[wpecards]

it always appears like this:
[wpecards]
intro copy, intro copy, intro copy

i read something about having to use “return” instead of “echo” in the plugin, but i didn’t write the plugin, nor am i a programmer.

here’s the code from the plugin that i *believe* is in question.

// Shortcode replacement
function ft_wp_ecard_insert(){
	global $wp_query;
	if ( is_page() || is_single() ){
		if ( class_exists('FT_WPECARDS') ){
			$cards = new FT_WPECARDS();
			if ( isset($wp_query->query_vars['ft_wpecards_view'])){
				$cards->load_card($wp_query->query_vars['card']);
				$cards->view_card();
			}elseif ( (!$cards->form_submitted) || ($cards->form_submitted && is_array($cards->error_messages)) ) {
				$cards->print_errors();
				$cards->print_form();
			};
		}
	}
}
add_shortcode( 'wpecards' , 'ft_wp_ecard_insert' );

i’ve tried everything but to no avail. can anyone help me so that i can get text to appear ABOVE the content that the shortcode generates?

thanks!!
