Hi,
Do you want that the name and id of the select boxes should be a variable $countrycode and the value assigned to it should be fetched from table.

Thanks!

Which Server Side scripting you are using.
If that is Java based then I can help other wise I can't.
If you want to get those values while the page gets processed on Server Side then it can be done simply using Server Side Scripting.
But if you want to get those information after the page loaded then you have to use Ajax.

i will select countrycode from select box and post this value using ajax ,php,javascript now this values is stored in $countrycode so while fetching the data for cities i'll use this to build query.

actually i have a main form on which both the select boxes are given and the country is filled with mysql country table
now i have used ajax and javascript to post this value without refreshing as i have n number of rows of this type and i can't aford let it refresh after evry rows country code is selected .
which is passed to country.js file through showcountry function
and from there to country.php to fetch the record for country details depending upon country code and display it .here i also want that depending upon the country code i want the city select box to be filled along with country details display
