No bro its not throwing error but its not being called either when we select the state from dropdown. This is the main issue. Please find some solution . You answer will be appreciated. If you want I can post the dropdown codes also.

You can check with your browser's developer tool to check the exact issue.

Open the page press F12 to open the developer's tool for IE/Mozilla/Chrome.
Click on the console tab in the developers tool.
Then select the States dropdown now you can see the error if any in the console window, and you can proceed to fix it.

Or else if you are still facing any problem then please post the code so that i can analyse the code to give you a proper solution.

I imaging that you have the value of select as 0(zero)

It is not getting called because of this below two lines

SQL

var selectedValue = $(this).val();
                  if(selectedValue != "Select") {

try this

SQL

var selectedValue = $(this).val();
                  if(selectedValue != "0") {
