Changing checkoout steps

[Basobaso]

Hello

 

I need to reorganize 5-steps order process in PS 1.5.4.1 for three steps:

 

1. step - summary * address (guest address form, or link for register/login)

2. shipping summary

3, payment & finish

 

I'm trying to add some .tpl files in my shopping-cart.tpl, but it semms it doesn't work 

 

i'm trying to add order-opc-new-account.tpl but the file is not displayed correctly

 

How can I do it ? And how to make just 5 steps. (changing order-steps.tpl & OrderController.php only ?)

 

Thanks for any advice !
