Removing asterisks around null seems to help with the errors but it doesn't look like the grammar is working: there are no parses or even parse charts produced.</div> <div class=""><br class=""> </div> <div class="">Would anyone be so kind to take a look and advise me as to how to update the toy grammar so it is working?
