jim.davidson Posted June 6, 2007 Author Share Posted June 6, 2007 Well it looks like I'm up the proverbial creek. The only thing I know about ajax is that it's good for cleaning porcelain. What I need to do is this. I have two dropdown list menuson the same form. One for countries, and one for states. I want to populate the second one (states) based on the country selected from the first menu..i.e. chose US and populate with US states, chose Canada, populate with canadian provinces. Is there a good tutorial somewhere that will help me? Link to comment https://forums.phpfreaks.com/topic/54439-variable-question/#findComment-269261 Share on other sites More sharing options...
