How I use procedures for a custom crafting block with multiple recipes?

I followed the step and have been successful at making a 3x3 crafting GUI however there are some issues I am having problems sorting out.

1. The recipe will always be the first recipe I use in the if statement. I have tried to use (else if) or just a new else statement both would just craft the first recipe on the list. The other thing I tried was to call a separate procedure from to the location of the blocks and that did not seem to have any effect what so ever and did not display a custom text error output I inserted for the test.
    
2. There is no way to know if the item is right as there is no dummy item in the GUI output slot. This makes it hard to know without pressing the craft button to be sure if its the right items in the right place.

If someone has a tutorial workspace I can learn from to set up a custom crafting block for more than one item it would be a great abundance of help.
