Well done on solving it yourself :-)
Remember, you can use upper() and lower() functions to transform the text too if you like...
:if(upper(my_password) == upper(computer_password)){ : print "CORRECT!"; }
Not to do with your question, but you might also want to use an alternate match for computer (in this case) too:
// I would probably type 'use computer', and not 'start computer' : match "start computer;use computer;switch computer;boot computer" { }
