Shortcode inside shortcode (displaying text and shortcode - error)

I have developed a custom short code, and am trying to get it to display the content of a child shortcode without actually outputting the text as well.

My shortcodes are as follows:

[member]

[gravityform id="1" name="Order Form" title="false" ajax="true"]

[/member]

Code (markup):

and my PHP function is as follows:

add_shortcode( 'member', 'member_check_shortcode' );

function member_check_shortcode( $atts, $content = null ) {
	 if ( is_user_logged_in() && !is_null( $content ) && !is_feed() )		
return $content.do_shortcode($content);
	return '';
}

PHP:

My output is 1/2 successful. It is displaying the contact form as it is supposed to.. however, it is also displaying the inside shortcode as plain text above it! I need only the form displayed.. not the tag that is including it. There must be something wrong with my function but i'm not sure exactly what.

EDIT:: Once again, solved my own issue. The if statement should return:

return $content.do_shortcode($content);

PHP:

 

It looks like it works fine? I don't see a prob???

 

Yes, my above edit fixed the issue. Thanks.

 

Oh, sorry about that. Was reading toooooo fast and didn't notice the edit below it...
