Restore iphone 4 with ios7?

I changed my password and then forgot it >< and i'm tryna restore it but itunes won't let me, its sayin i needa go on settings and turn off find my iphone… But obviously i can't, what to do?

If you go to iCloud.com/find and login, you will be able to remove the phone from your iCloud account. That should allow you to then restore the iPhone as needed to resolve the issue. Hope this helps!
