HELP - Cloning Per Item Shipping. Showing up but one doesn't work!

[zhoos]

Hello all,

I'm stumped here and could use some help. I'm setting up two kinds of PER ITEM shipping methods for our store.
1. Standard Shipping, and
2. Priority/Registered Shipping (with slightly higher rates)

To do this, I basically copied the Per Item Shipping and changed most of the ITEM to ITEM 2. That was a great idea, and in my checkout page both of them were showing.

HOWEVER, in my checkout page STEP 2, where you choose your shipping method, if I choose the original Standard Shipping (no mods at all) and click on next to go to STEP 3, the page reloads itself and does not proceed.

If I choose the new cloned Priority/Registered Shipping, and click to go to STEP 3, it WORKS!

So why doesn't the first module work anymore? I'm attaching my codes below, please do help this poor soul in need! Thanks!

You appear to have changed the original code in item.php file ...

I don't get it. I thought to clone it we were supposed to change some of the code?

Like - Item I changed it to Item2?

Otherwise it won't work, will it?

[Ajeh]

I am talking about the original file item.php ...

You have:
class ITEM

that is not the original code ...

Check and see if you accidentally changed the original file item.php from the original code ...
