I am trying triple drop down menu first and second menus are working but third one is not working and also the data is not being displayed on the web-page even though I have used "echo" command. I am unsure what is the problem and how to correct it. So I am attaching my code in this email, could you please look into it and help me with it.
I have 1st drop menu for State : Tennessee Alabama Georgia
2nd Drop down list for County: Anderson Bredford Benton
3rd Drop down list for Genus Acer Aristida
Eg: Tennessee -> Anderson, Bredford, Benton and Anderson -> Acer, Aristida and when I select Tennessee->Anderson->Acer it has to display all the information of the table based on these selected values.
Could you please help me with this.
