Why doesn't my struct code work?

package app

type ConfigSet struct {
	installed bool
}

import (
	"fmt"
	"html/template"
	"net/http"
)

func init() {
	config := ConfigSet{}
	
	// -------------------------------------- //
	//             CONFIGURATION              //
	// -------------------------------------- //

	// Change to "true" after configuration is done!
	config.installed = false

	// -------------------------------------- //
	//           END CONFIGURATION            //
	// -------------------------------------- //
	
	http.HandleFunc("/", index)
	http.HandleFunc("/index.php", index)
}

func index(w http.ResponseWriter, r *http.Request) {
	if config.installed == false {
		w.Header().Set("Location", "/install/")
		return
	}
}

I can't seem to figure out why this doesn't work. The error I get is:

2012/05/21 13:22:01 go-app-builder: Failed parsing input (1 error)
2012/05/21 13:22:01 /root/TravianGAE/app/app.go:7:1: expected declaration, found 'import'

I don't understand, am I supposed to declare anything there?

Put your import first, before the type.
