loop for s and loop for Inp should be different. Don't you think?
how many select object with City information do you have? if just one, why don't you give it a id. and the one object with s=document.getElementById("select_id"); value would be s.value; simple as it is.

C#

if(selected_index > 0)
{
   var selected_option_value = oForm.elements["country"].options[selected_index].value;
   var selected_option_text = oForm.elements["country"].options[selected_index].text;
}
else
{
   alert('Please select a country from the drop down list');
}
