I am stuck when it comes to adding more than one search element. I can get 1 search element to work using the Fusion tables layer wizard but any others added don't function? My website is called earthquakedamagemap.com. I'm trying to build a similar search function to that of newspapermap.com
It is my university project. Any advice would be much appreciated!
Try changing the id of your second select menu to search-string1. Then, in your changeMap1 function, pass 'search-string1' to the method document.getElementById().
