i want to go from one page to another in my website using a button.
my code for this is like the following:

```
 self.response.out.write('''<form
        action="/sign" method=post> <br><input type=submit value="go to lesson 2 ">
        </form>  
''') % self.redirect("/lesson1")

```

now i am in lesson one page and i want using this button to go to lesson1 page but i keep getting this error:
PyDev breakpoint
inconsistent dedent at line 53, column 2
Bad Indentation (7 spaces)

does any one know how to fix this?

thanks 
Amal
