Reply To: Read More button with handcrafted excerpt

I have read the Studio Press snippet and your suggestions, as well as the looking at the code in the portfolio.php file and I don’t get it.

I have tried adding add_filter( 'get_the_content_more_link', 'portfolio_read_more_link' ); to the existing list of three filters. It doesn’t do anything and appears duplicative of what was has already coded in.

I tried just adding add_filter( 'excerpt', 'portfolio_read_more_link' ); to the 3 existing filters, nothing.

I copied and pasted the entire code from studio press into the file; nothing.

I don’t understand what your telling me I need to do to get this.
