// Usage: find_query_string(name)
//
// name - the name of the variables to get from the query string
//
// This function searches for the specified variable name in the
// list of variables which were given in the URL of the page (also
// called the QUERY_STRING).
//
// If the variable cannot be found, the function returns the string
// 'undefined' (because I.E. does not support the keyword properly)
//
