[FX.php List] Javascript & PHP

[Scott Baetz]

Chuck,

I believe this is easier than you might think.  First, I strongly 
recommend a good web search on this matter.  I've found that 
www.JavaScript.com can provide a number of good leads in the right 
direction. 

At the core of this situation, you might ask yourself, how is this going 
to be structured?  Frankly you should create your two related 
javascript'ed menus without PHP first (I only suggest this as you are 
indicating that you are learning JavaScript as you go).  With this basic 
coding mastered, you will realize that as Michael mentions below, you 
are simple going to load the data values from a standard FXphp call.  
BAM you are done.

Best regards,

Scott Baetz
