Mr T.: No offence, but _please_ inspect the questions more before resonding!! You're giving everyone wrong answers!

Hi. Your problem lies in the vocab. Sierra originally grouped the words "look" and "read" together. That being the case, typing "read" will always be the same as "look", as well as "display", etc.
To fix it, simply load the vocab.000 ("Words") vocab in the Vocabulary Editor, go "Find Word"->"look" then remove the word "read" from the look group, and create a new group, placing it in there. Finally, recompile the script(s) using the "read" word.
