I have spent a long time on this and still cant figure out whats wrong. I have recently started with javscript and my question is as follows:
The page works fine but if the User selects DVD from the dropdown and doesnt type anything in the 2 text fields, it should display an alert. Its working fine for the other options in the drop down, only this does not work.
Would greatly appreciate if someone can enlighten me on this... thanks.
