Quiz

1.)This writes a random question to the page and provides a check box, however i would like to be able to provide immediate feedback, for example, when they check the box I can display in writing weather what they chose was wrong

2.) My function down the bottom opens a new windows with another new question, however the question somtimes repeats I need to somehow keep the questions random, the .sort math random function does this, but as im loading in a new window the JS starts over again and so arrays already been used are back in

Any help would be much aprreciated. I know I am brand new just looking for a lifeline

Some sort of onclick event? have a read of this...

For the second part, does this have to be (almost) purely javascript? why not create a form instead and you can pass a (hidden) value and make sure not to start with that question next time?
